Apache Tez is a modern data processing engine designed for YARN on Apache Hadoop 2. Tez aims to provide high performance and efficiency out of the box, across the spectrum of low latency queries and heavy-weight batch processing. It provides a sophisticated topology API, advanced scheduling and concurrency control & fault tolerance. With a clear separation between the logical app layer and the physical data movement layer, Tez is designed from the ground up to be a platform on top of which a variety of domain specific applications can be built. Tez has pluggable control and data planes that allow users to plug in custom data transfer technologies, concurrency-control and scheduling policies to meet their exact requirements.

The talk will cover real use cases from adopters like Hive, Pig and Cascading and provide data to show the performance of Tez.

Using Websocket With CXF And Camel - Akitoshi Yoshida, SAP

WebSocket is a full-duplex transport protocol developed as part of HTML5 and has caught attention not only for Browser applications but also also for application integration. This simple HTTP based protocol can operate over a single socket and does not suffer from network restriction such as proxies and firewalls when establishing a duplex channel.

New WebSocket support in Apache CXF can be used to invoke an asynchronous JAX-WS service over a single WebSocket connection instead of using two separate HTTP connections, to establish a direct node connection in a cluster environment, and to asynchronously push data from a JAX-RS service to its client. And Apache Camel now supporting both the client and server side WebSockets can be used to integrate and compose various WebSocket applications with other applications.

Putting The C Back In CouchDB 2.0: Merging Bigcouch - Joan Touzet, Cloudant

Apache CouchDB - an acronym for Cluster Of Unreliable Commodity Hardware - is a database that uses JSON for documents, JavaScript for MapReduce indexes, and regular HTTP for its API. To date, individual servers support multi-master replication, but do not actually act as a server cluster. In this presentation, Joan Touzet will cover the recent merge of the BigCouch fork in advance of the release of CouchDB 2.0. This significant work enhances CouchDB with a native Erlang-based clustering mechanism, supporting high availability, database partitioning and DynamoDB-inspired enhanced read/write semantics.

Introduction To A Groovy Based DSL For Apache OFBiz - Jacopo Cappellato, HotWax Media

Apache OFBiz is a framework and a suite of applications for the automation of enterprise tasks (e.g. ERP, CRM, MRP, E-Commerce). Although usable out of the box, OFBiz often requires the customization of some of its components for managing specific business processes. In order to rapidly and effectively integrate new functionalities, developers need a programming environment that allows to focus on the business logic without being distracted by low level coding details. Up to now, the best practice has been to use Minilang, an xml based Domain Specific Language (DSL) developed by the OFBiz community, together with plain Java and Groovy, when more flexibility is needed. In this presentation, Jacopo Cappellato will outline the limitations of the current approach and will propose a new Groovy based DSL that could become the only language you'll need to know for the customization of OFBiz.

Long-Lived Yarn Services: The Future Of Yarn Applications. - Steve Loughran, Hortonworks

Apache Hadoop clusters are generally viewed as data analysis systems, running short-to medium life analysis applications —or installations of a single large application such as Apache HBase & Apache Accumulo.

There's no reason for this to be the case: you can deploy long lived services into a Hadoop cluster, gaining access to the HDFS filesystem, availability from a fault-resilient infrastructure, shared use driven by scheduling -and the ability to integrate with other services running in the YARN cluster.

In this talk I will look at the needs of long-lived services, where YARN is today with supporting them -and where we are going next. In particular, I will explore the JIRA issue YARN-896 is the focal point for evolving YARN's support of long-lived services, addressing needs such as security, logging and service discovery -demonstrating some of this in action.

Building A Better Test Platform: A Case Study Of Improving Apache Hbase Testing With Docker - Aleks Shulman & Dima Spivak, Cloudera

Cloudera Engineering has heavily incorporated Docker, an extension of Linux Containers, into our integration testing framework for Apache HBase, a distributed "NoSQL" datastore. Through the use of Docker images, we have succeeded in parameterizing the Apache Hadoop environment on which our tests are deployed. This allows us to test functionality and compatibility across a wider range of platforms in a much shorter amount of time, resulting in dramatic improvements in utilization of our computational resources. In this talk, we will present how we use Docker during test development to reduce the time it takes to write and run functional tests and to include more test configurations. We will then go in-depth on a particularly novel use case: compatibility testing. Attendees will come away with a perspective on Docker that will help them adopt it into their own test frameworks.

Particle Physics On The Couch: Using CouchDB To Help Unravel The Mysteries Of The Universe - Michael Marino, Echnische Universität München

Pushing the envelope of our understanding of the universe requires physics experiments that measure and analyze data from many disparate systems. Such systems generally have widely different requirements and architectures, making it difficult to implement a single, monolithic program for control and readout. CouchDB is an optimal tool to integrate and save data from such systems since its RESTful interface provides a minimal hurdle that almost all devices large and small can achieve. In this presentation, Mike Marino will describe how CouchDB is being used in the nEDM experiment at the Technische Universität München to integrate, control, view and save measurement data from many different subsystems, ranging from those powered by microcontrollers and mini PCs (Arduinos and Raspberry Pis) to those based on the industrial VMEbus.

CouchDB-Based System For The Users Data Management In Cms At Lhc: Implementation And Experience - Hassen Riahi, CERN

The Compact Muon Solenoid (CMS) users data management service at The Large Hadron Collider (LHC), named AsyncStageOut, manages more than 300k users' files per day of close to 1000 individual users per month with minimal delays, and providing a real time monitoring to users and service operators, while being highly available. The associated data volume represents a new set of challenges in the areas of database scalability and service performance and efficiency.
The service is designed as a thin application relying only on CouchDB as input and data storage. It has progressed from a limited prototype to a highly adaptable service, which manages and monitors the whole CMS user files steps.
In this presentation, Hassen Riahi will provide an overview of the AsyncStageOut model, present the motivations for using CouchDB, describe the deployment model and discuss the results achieved.

Introduction To A Recommender System For Apache OFBiz - Anahita Goljahani

Recommender Systems are engines aimed at predicting users preferences based, e.g., on knowledge about past behaviors of similar users. Recommender Systems have become very popular in the recent years, e.g., to suggest products to buy, articles to read or music to listen. One of the main advantages of Recommendations is that they allow users to discover items that a simple search might not show up. This is one of the reasons why Recommendation engines have become a desirable, if not essential, component of commercial platforms.

In this presentation, Anahita Goljahani will discuss the design of a Recommender System for Apache OFBiz (http://ofbiz.apache.org/), the popular solution for the automation of business applications (ERP, CRM, MRP, E-Commerce, etc.).

Lucene, while a mature and proven technology, has gotten little press in the NoSQL buzz. What started as a full-text search index solution has grown to also be the basis for Solr and ElasticSearch. Most importantly for today's talk they have added the capability to do spatial queries along with full text queries. In this talk I will give a quick intro to Lucene and surrounding projects, give it's sweet spot for use, and then give a quick code sample on indexing and searching of a spatial document collection. The code will use Java, JAX-RS, and CDI to create a geospatial REST service talking to a JavaScript Front-End using Leaflet and OpenStreetMap.

Building Your Own BaaS With Apache Usergrid & Docker: Lessons Learned At Scale - Sungju Jin, Korea Telecom

BaaS(Backends-as-a-Service) and PaaS(Platforms-as-a-Service) are not just for hipsters anymore. 2013 saw many people building their own PaaS like Heroku, Cloudfoundry or BaaS like Parse, Kinvey.

However, many companies and open-source projects only focus on the advantages of building your own *aaS and the advantages of their own solution. Do we really know what works and what should be considered when building such system? Many people do not know whether they should build a PaaS or BaaS, how they should build it, or even if they should build one at all.

Continuous Automated Deployment With Apache Ace - Jan Willem Janssen & Marcel Offermans, Luminis Technologies

Nowadays, it is quite common to have build infrastructure that, on every change in a repository, builds your software and runs all your tests. However this is where most development teams stop. This talk demonstrates how you can consistently deploy systems from development to testing, staging and production.
With Bndtools we semantically version bundles in the Eclipse IDE. The continuous build is setup to automatically deploy to a bundle repository and create snapshots of changed bundles compared to a baselined version that is available in a release repository. By hooking up these repositories to Apache ACE, such updates can instantly be deployed to systems in different configurations, allowing you to deploy new features to QA systems, beta users and finally roll them out to all other customers.
We’ll also go into real life scenarios and pitfalls we have encountered setting this up.

Anatomy Of An Apache OpenOffice Extension - Pedro Giffuni, Apache Software Foundation

Developing code within the huge, and sometimes daunting, Apache OpenOffice code can sometimes be very difficult, specially if you only want to add a very specific piece of code that few people want.
As part of an ongoing effort to improve the Operation Research capabilities within Apache OpenOffice, I will try to document the different parts of an Apache OpenOffice extension.

Apache OpenOffice supports a framework called UNO, Universal Network Objects, for developing extensions. Extensions can be written in C/C++, Python or Java.

The UNO documentation is somewhat sparse and most of the developers end up taking some existing extension and use it as a template to write their own. This introductory talk will consider the characteristics behind UNO and will provide the basics to write such applications.

The Flink Big Data Analytics Platform - Márton Balassi, Hungarian Academy of Sciences & Gyula Fóra

Apache Incubator Flink is a next-generation platform for big data analysis originating from the Stratosphere project (www.stratosphere.eu). Flink offers an alternative runtime engine to Hadoop MapReduce, but uses HDFS for data storage and runs on top of YARN. Flink`s runtime streams data rather than processing them in batch, uses out-of-core implementations for data-parallel processing tasks, degrading to disk if main memory is not sufficient. Flink is programmable via a Java or Scala API that includes functional operators like map, reduce, join, cogroup, and cross. Analysis logic is specified without the need of linking user-defined functions. Flink includes a cost-based program optimizer that picks data shipping strategies. Finally, Flink features support for iterative programs and graph processing programs. As a consequence Flink is currently witnessing its first commercial use cases.

Apache Bigtop: Saving The Day For Spark And Others - Roman Shaposhnik, Pivotal

Building a working data processing stack using open source or commercial components is a challenging and highly complex task. Multiple often conflicting dependencies, many development teams with different release trains might dictate a substantial coordination effort. A constant flow of new features, bug fixes, and other changes are almost a disaster in making when it comes to the regression and quality control at any stage between development and production environment. Businesses with internal development teams are facing the issues with integration points of their deliverables into the bigger, company wide data platform software. The problem is exaggerated by exponential growth of the standard libraries and transient dependencies. Oftentimes, it is next to impossible to create a well controlled and reproducible system environment in all stages of the platform life-cycle.

Time Series Data With Apache Cassandra - Eric Evans, OpenNMS Group

Whether it's statistics, astronomy, finance, or network management, time series data plays a critical role in analytics and forecasting. Yet, while many tools exist, few are able to scale past memory limits; For those challenged by large volumes of data, there is much room for improvement.

Apache Cassandra is a fully distributed second-generation database. Cassandra stores data in key-sorted order making it ideal for time series, and its high throughput and linear scalability make it well suited to very large data sets.

This talk will cover some of the requirements and challenges of large scale time series storage and analysis. Cassandra data and query modeling for this use-case will be discussed, and Newts, an open source Cassandra-based time series store under development at The OpenNMS Group will be introduced.

Security As A Service Leveraged By Apache Projects - Oliver Wulff, Talend

This talk illustrates how you can build a Security solution for Web Applications and Web Services by combining different Apache Projects. This solution can be used for internal applications and applications hosted in the cloud by supporting federation.
The talk focus on the Apache Projects CXF/Fediz and Syncope. Apache Fediz is a subproject of the CXF project which provides a Web Services standard with wide range on WS-* support in the security space. Fediz on the one hand provides Web Application SSO and on the other hand integrates with the CXF Web Services security layer. This allows to support impersonation end-to-end based on industry standards. Apache Syncope is a perfect combination to CXF and Fediz to provide a tooling to manage identities and its permissions.
The talk finishes with the demonstration of the stack CXF, Fediz and Syncope.

Enabling IoT With Apache Etch And Coap - Giorgio Zoppi, Universitat Pompeu Fabra

The talk introduces the work that we have done about Apache Etch framework and shows the simple steps which have to be done to enable an application to be used as part of the Internet of the things with COAP Protocol.
It shows the features of Etch, such as fully bidirectional client to server communication, synchronous and asynchronous calls, data modelling, error handling and performance and its new binding with COAP as transport protocol. Adding this new protocol to Apache Etch enables its stack to communicate efficiently with Internet Web of Things in language neutral way. The Apache Ecosystem will benefit from those changes to Etch, because it will have a new way to implement network services for constrained resources network (i.e. wireless network or sensor networks).

Multi Language Content Discovery Through Entity Driven Search - Antonio Morales, Zaizi

This presentation is about a Semantic Search Engine built on top of an Apache projects stack.
The scope of the system is to extract content from heterogeneus data sources, process and enrich it , index it and search over this content with advanced User Experience.
This result is achieved with the integration of 4 top level Apache projects : ManifoldCF, Stanbol, Marmotta and Solr.

Apache Manifold is used to access different data sources and extract the content from them: it's the engine that moves the main indexer core of the system. The document extracted are processed in a pipe-line manner, here happens the integration with Apache Stanbol and Apache Marmotta that allows the semantic enrichment of the content according to any Linked Data assets.
The last ring of the chain is custom Search API built on top of Apache Solr that allows advanced search features to improve user experience

How to Turn Your Favorite Programming Language Into An AOO Macro Language - Rony Flatscher, WU Vienna

Apache OpenOffice (AOO) defines a scripting framework that can be exploited to add any programming language to Apache OpenOffice as a macro language. This presentation introduces the necessary overview and knowhow to become able to assess the effort to add your own favorite programming language to AOO. Although the AOO scripting framework is implemented in Java it is possible to add non-Java-implemented programming languages as demonstrated with the programming ooRexx which is itself implemented in C++. In addition all scripting languages that support Java's "javax.script" framework could be added to AOO using AOO's scripting framework.

OSGi For Mere Mortals - Bertrand Delacretaz, Adobe

In the last few years, OSGi has become ""the"" module system for Java - but is OSGi just for gurus, or are mere mortals actually able to use it?
The simple tutorial RESTful server application presented in this talk aims to demonstrate that the average Java developer can actually use OSGi, and greatly benefit from it. It is built from scratch based on a set of standard and custom OSGi services, in a simple and understandable way.
Taking advantage of a number of build plugins and runtime tools provided by the Apache Felix and Apache Sling projects allows us to write little code in our example application, while exposing the advantages of an OSGi-based architecture in a simple and convincing way.

Apache Giraph: Start Analyzing Graph Relationships In Your Big Data In 45 Minutes (Or Your Money Back)! - Roman Shaposhnik, Pivotal

The genesis of Hadoop was in analyzing massive amounts of data with a mapreduce framework. SQL-onHadoop has followed shortly after that, paving a way to the whole schema-on-read notion. Discovering graph relationship in your data is the next logical step. Apache Giraph (modeled on Google’s Pregel) lets you apply the power of BSP approach to the unstructured data. In this talk we will focus on practical advice of how to get up and running with Apache Giraph, start analyzing simple data sets with built-in algorithms and finally how to implement your own graph processing applications using the APIs provided by the project. We will then dive into how Giraph integrates with the Hadoop ecosystem (Hive, HBase, Accumulo, etc.) and will also provide a whirlwind tour of Giraph architecture.

LDAP Testing: Does It Have To Be A Nightmare? - Emmanuel Lecharny, Symas

When it comes to testing the LDAP part of an application, it's usually a task that is seen as a punishment by many developpers. The JNDI API does not help, nor does the fact most of the time, you have to reset your LDAP server between each test.

We will expose a better way to do LDAP based tests.

Apache Directory Server has some revert mechanisms that spare developers the need of resetting the LDPA server between tests. We also have a full annotation based solution to initialize a LDAP server in unit tests.

Apache LDAP API is way simpler than JNDI and has extended features that makes it easer to use for any Java developper.

We will present those features with simple tests and some more complex.

OSv: Probably The Best OS For Cloud Workloads You've Never Heard Of - Roman Shaposhnik, Pivotal

OSv is the revolutionary new open source technology that combines the power of virtualization and micro-services architecture. This combination allows unmodified applications deployed in a virtualized environment to outperform bare-metal deployments. Yes. You've heard it right: for the first time ever we can stop asking the question of how much performance would I lose if I virtualize. OSv lets you ask a different question: how much would my application gain in performance if I virtualize it. This talk will start by looking into the architecture of OSv and the kind of optimizations it makes possible for native, unmodified applications. We will then focus on JVM-specific optimizations and specifically on speedups available to ASF projects when they are deployed on OSv

Lizard - Clustering An RDF Triplestore - Andy Seaborne, Epimorphics Ltd

This is the story of building a clustered SPARQL database. Demand on
triplestores is growing, both in terms of scale and reliable operation.
Replication and clustering are needed for fault tolerant operation and for
larger datasets. Server replication of a single machine database only get so far.
It is easier to have a system designed to harness the capabilities of
several machines in one system. The goal of ""Lizard"" is to provide a solid
platform for triplestore operation.

In this presentation, Andy will describe how ""Lizard"" takes the Apache Jena
TDB database design and extends it to cluster operation. The talk will
cover the core principles of the TDB design and SPARQL execution, the
choices to be made in the ""Lizard"" design that rework the system for a

What's With The 1S And 0S? Making Sense Of Binary Data At Scale With Tika And Friends - Nick Burch, Quanticate

If you have one or two files, you can take the time to manually work out what they are, what they contain, and how to get the useful bits out (probably....). However, this approach really doesn't scale, mechanical turks or no! Luckily, there are Apache projects out there which can help!

In this talk, we'll first look at how we can work out what a given blob of 1s and 0s actually is, be it textual or binary. We'll then see how to extract common metadata from it, along with text, embedded resources, images, and maybe even the kitchen sink! We'll see how to do all of this with Apache Tika, and how to dive down to the underlying libraries (including its Apache friends like POI and PDFBox) for specialist cases. Finally, we'll look a little bit about how to roll this all out on a Big Data or Large-Search case.

“Your Search Doesn’t Work.” - How to Find Out Whether or Not the Search Box You Offer Users is Helping - Isabel Drost-Fromm, Elasticsearch

Web sites without search functionality are unimaginable today - you search for comments and code on github, you look for books in your favourite webshop, you use the search box of your favourite blog to find articles.

When offering your search for your own application - how do you know that your search actually provides a benefit to the user instead of causing lots of frustration over results not found? Only checking that the favourite book about witches of your child is ranked top of all children books clearly doesn’t help.

This talk will walk you through the options of determining search quality - from purely offline metrics that work even before deploying version 1.0 to production to online A/B testing to check continuous improvement. I will highlight some Lucene and Elasticsearch features that can tremendously help you deploy your own search quality checks.

OSGi Remote Services In A Microservices World - Marcel Offermans, Luminis Technologies

In a Microservices architecture applications get decomposed into functionally cohesive services that are implemented as separate processes that interact through the network using simple protocols. This allows applications to scale during deployment by distributing and replicating the services across compute resources as required.

However popular, common criticism includes the use of implicit and poorly defined interfaces, the fact that every component must implement remoting concerns and the fact that it introduces significant processing overhead as every service invocation traverses the network, even if the services are on the same box!

In this presentation we discuss how OSGi Remote Services can address these concerns in an OSGi context by providing the developer strongly typed services that may or may not actually be transparently remoted across a scaled-out deployment.

Introduction To Apache Slider - Steve Loughran, Hortonworks

With YARN, Apache Hadoop can deploy distributed applications —applications which can dynamically expand or contract their size based on demand or other factors. It allows the application to choose the placement of distributed components within the cluster, as well as their resource requirements such as CPUs and memory. As YARN evolves to support long-lived services, YARN applications can become services supporting broader uses.

Taking advantage of these features has required the application to be rewritten as a YARN application, central to which is the Application Master —a process which manages the allocation of components across the cluster, deployment of these components, as well as failure handling.

The Apache Slider project can deploy distributed applications without requiring them to be ported to YARN: Slider provides the Application Master and the allocation, deplo

Cloud Storage With Apache jclouds - Andrew Gaul

Object stores provide a flexible, scalable, and cost-effective abstraction to build applications in both the public and private cloud. Apache jclouds abstracts all major providers, allowing Java source-level compatibility while providing access to vendor-specific interfaces. This talk will cover how to integrate jclouds into applications and how to manage containers and objects. It will also discuss differences between providers, scaling out the number of clients and number of objects, and tradeoffs in application design.

Improved OVA Support In CloudStack - Likitha Shetty, Citrix

Improved OVA support in CloudStack’ is a feature targeted for the 4.5 release of CloudStack. With this feature in place, users will be able to on-board an existing Virtual Machine into CloudStack with all of its disks intact.

The talk will focus on the architectural and design changes that will be made and on the new concepts that will be introduced into CloudStack as part of this feature. In addition, the talk will cover what the initial approach to the problem was and how based on community feedback it evolved into a better solution that aligns with how resources are traditionally created and orchestrated in CloudStack. It will also shed some light on how we could leverage this development work to add new functionalities going forward for e.g. adding support for other information encapsulated in an OVA like ISOs, networks, device controller types etc.

Quadrupling Your Elephants - RDF And The Hadoop Ecosystem - Rob Vesse, YarcData

The Hadoop ecosystem is excellent in providing a large variety of data processing paradigms and supports a wide variety of data formats. However support for RDF within this ecosystem is often non-existent or confined to academic research which has yet to make the jump to production ready systems. In this talk I will present several projects I've been involved in both inside and outside the ASF which are looking at bringing production ready RDF support to the Hadoop ecosystem.

Felix Http - Paving The Road To The Future - Jan Willem Janssen & Marcel Offermans, Luminis Technologies

Developing modular web-based applications is easy using the HTTP-service implementation of Apache Felix. It hides the complexity and boilerplate code needed to get your servlets and filters up and running in no-time. With the recent effort in aligning the HTTP-service with the latest servlet specifications, new functionality like asynchronous servlets and filters will be supported out-of-the-box.
In this presentation we will not only talk about the new features provided by the Felix HTTP-service implementation, but also demonstrate how to use them in your project. In addition, we talk about upcoming improvements to the Felix HTTP-service, like native support for SPDY and WebSockets.

The Other Apache Technologies Your Big Data Solution Needs - Nick Burch, Quanticate

In this talk, we'll take a look at a range of projects from the Apache Software Foundation, looking at those which complement the "headline projects" to build out your big data solution. While we can't cover every project at Apache (there are just too many these days!), we'll take a tour through some of the up-coming and lesser-known established projects out there, those that should prove very helpful to you in building your big data solution. We'll see that Apache is more than just the webserver, Hadoop and Lucene, and with any luck point you at projects that'll save you time and effort!

Taming The Cloud Database With Apache jclouds - Zack Shoylev, Rackspace

Managing application infrastructure is not what developers want to spend time figuring out. The challenge of quickly automating facets of application development such as database infrastructure setup is still present in many cloud application projects. This presentation will introduce developers to current cloud services (private and public clouds, terminology, service types, OpenStack) and relevant Java SDKs. This will include discussing the advantages of using open source, portable, and provider-agnostic solutions versus more closed systems. The talk will describe high-level jclouds architecture and present code examples to manage cloud-based database infrastructure using OpenStack Trove. Due to popular demand, a short tutorial on implementing abstraction layers and custom APIs for databases in jclouds will also be presented.

Speakers

Towards a Commons RDF Library - Sergio Fernández, Redlink GmbH

In the Java world there is an historical incompatibility issue between the two major RDF toolkits: Apache Jena and OpenRDF Sesame. But behind this effort there is a completely different approach than before. This library does not pretend to be a generic API wrapping those libraries, but a set of interfaces for the RDF 1.1 concepts that can be used to expose cores concepts using common Java interfaces. In the initial phase commons-rdf is focused on a subset of the core concepts defined by RDF 1.1 (URI/IRI, Blank Node, Literal, Triple, and Graph). In particular, Commons RDF aims to provide a type-safe, non-general API that covers RDF 1.1. In a future phase we may define interfaces for Datasets or Quads.

Counts in core contributors from both Jena and Sesame, But it will live or die on its own merits!

The working repository can be found at http://github.com/wikier/commons-rdf

How Secure Is Your Web Framework? - Lukasz Lenart, ASF

In this talk I would like to present few recently discovered security vulnerabilities in the Apache Struts 2 web framework and based on that try to increase developers' awareness of the overall application security. In my opinion, nowadays developers don’t care about the security too much, they depend on what the framework gives them. Quite often, they even don’t check security bulletins to see if a new vulnerability wasn’t discovered recently in his/her famous framework. I would like show few web attacks and explain how it was possible to harm an application or even entire server, how to prevent such kind of attacks in the future and so on. Examples will base on the Apache Struts 2, but almost all the same problems were pointed out in the Spring MVC or in the Apache Wicket. Each framework has its own weaknesses :-)
