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. Special attention will be given to new functionality, operational considerations from Cloudant's experience running this code for years in production, upgrade scenarios for existing users and the exciting new Fauxton UI.

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.

From OAuth1 To OAuth2 With Apache CXF And Hawk - Sergey Beryozkin, Talend

OAuth2 is a set of specifications describing the way resource owners can allow third party applications access some of their resources. OAuth2 owes a lot to the popularity of older OAuth1, the fact which led to the OAuth2 process being initiated. However the concern about OAuth2 being as capable and secure as OAuth1 is still shared by some developers. In this presentation we will briefly introduce Apache CXF OAuth2 implementation and show how OAuth2 and Hawk (Mac) token can be used to create simpler and no less secure classical OAuth applications.

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.

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.).

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 Zookeeper In The Wild - Rakesh Radhakrishnan, Huawei Technologies

A high-performance centralized coordination service is a critical component for any distributed application. Apache Zookeeper is such a component and it has been in the past few years a practical solution to cluster coordination.

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.

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

JBatch++ With Apache BatchEE - Mark Struberg

Apache BatchEE is an implementation of the JSR-352 JBatch specification.

BatchEE is based on the original reference implementation but includes many bug-fixes and improvements.
In addition to the jbatch core module we also added many useful helpers which do make batch programming a breeze.
We did also add a few ways to control your batch jobs, e.g. via JAX-RS, a simple GUI or even as stand-alone command line client. That way you can use BatchEE in JavaEE 5, 6 and 7 environments and even in Java SE.

After an introduction to writing JBatch batches in general we will showcase fancy features of BatchEE and we surely have some best-practice tips to share.

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
medium scale cluster system, and report of the current status.

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.

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

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!

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 :-)
