Apache Tez - A New Chapter In Hadoop Data Processing - Hitesh Shah, Hortonworks
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.

Accelerating Big Data Application Development With Cascading - Supreet Oberoi, Concurrent, Inc.
Cascading is a Java-based application development framework for building Big Data applications on Apache Hadoop. This open source framework allows developers to leverage their existing skillsets such as Java, SQL, etc. to create enterprise=grade applications without having to think in MapReduce. This comprehensive framework separates business logic from integration logic so that developers can quickly build and test data applications locally on their laptop and then deploy them on Hadoop. While typical enterprise data applications must cross through multiple departments and frameworks, Cascading allows multiple departments to seamlessly integrate their application components into one single data processing application. In this presentation, developers will get an introduction to Cascading, how it works, and then dive into how one can build applications with Cascading

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.

Ndfs: A Native Client For The Hadoop Distributed Filesystem - Colin McCabe, Cloudera
As the main filesystem for Hadoop, the Hadoop Distributed Filesystem an important part of the big data ecosystem. However, previously, non-Java Hadoop clients have had to deal with the JNI interface when communicating with HDFS. NDFS, our new project to create a native client for HDFS, offers many operational, performance, and practical advantages for these clients. In this presentation, I'll talk about the architecture of NDFS, the problems we solved when developing it, and our plans for the future.

Scalable Stream Processing With Apache Samza And Apache Kafka - Martin Kleppmann, LinkedIn
Samza, an Apache Incubator project, is a framework for processing and analysing high-volume data streams. It is built upon Apache Kafka and YARN (Hadoop 2.0). You can think of Samza as a real-time, continuously running version of MapReduce.

In this talk, Martin will show why stream processing is becoming an important part of the architecture of data-intensive applications, alongside storage and batch processing. We will explore how Samza works, and show how it reliably processes millions of messages per second. We will also examine what kinds of applications would benefit from using Samza.

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.

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.

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.

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

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.

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

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!
