Random Forest Clustering with Apache Spark - Erik Erlandson, Red Hat, Inc.
Analytics applications often boil down to grouping objects into two or more clusters having similar elements. Defining what “similar” means can be surprisingly difficult when data elements have many columns or dimensions. Having tools at hand to generate quality clusters from high-dimensional data greatly increases the variety of applications that can successfully leverage clustering.

In this presentation, Erik Erlandson will introduce the basic principles and advantages of Random Forest learning models and Random Forest clustering. He will explain how to build up an implementation of Random Forest clustering in the Apache Spark analytics framework, based on the Spark MLLib Random Forest modeling API.

The presentation will include examples of Random Forest clustering applied to VM installed-package profiles and a discussion of practical issues encountered along the way.

Clickstream Analysis with Apache Spark - Andreas Zitzelsberger, QAware GmbH
On large-scale web sites, users leave thousands of traces every second. Businesses need to process and interpret these traces in real-time to be able to react on the behavior of their users.
In this talk, Andreas will show a real world example of the power of a modern open-source stack.
He will walk you through the design of a real-time clickstream analysis PAAS solution based on Apache Spark, Kafka, Parquet and HDFS, explain our decision making and present our lessons learned.

Spark Cyborgs - Deep Integration of Spark with Parallel Relational Engines - Torsten Steinbach & Gustavo Arocena, IBM
In this session we describe a family of hybrid engines that result from a deep two-way integration between Spark and parallel RDBMSs. This integration differs from projects like Hive on Spark, that leverage Spark purely as an execution framework. It also goes beyond what’s possible with the current version of the DataSources API in terms of leveraging the capabilities of the storage backend. In our presentation you will learn about four essential building blocks of the hybrid engines:
1. Derive DataFrame partitioning implicitly from parallel RDBMS partitioning
2. Colocation and efficient data movement between Spark and RDBMS processes
3. Hybrid queries by augmenting parallel RDBMS with Spark
4. Spark machine learning integrated in RDBMS for relational data

On the Fly Retraining of Predictive Analytical Models Using Spark Streaming: An Equity-price Direction Prediction Case Study - Tijl Carpels, Ghent University
FinTech companies are facing the challenge of predicting the direction of equity prices. During this study we have used algorithms provided in Spark Mllib to address this problem. Due to the characteristics of the equity market this happens in a streaming environment requiring us to continuously monitor the performance of the predictive model. When the performance drops below a certain threshold we trigger a batch training of the model. We made a proof of concept using different open-source tools. (Apache Spark and Spark-notebook)

Real Time BOM Explosions with Apache Solr and Spark - Andreas Zitzelsberger, QAware GmbH
Bill of materials (BOMs) are at the heart of every manufacturing process. Especially large BOMs can be found in the automotive industry, where a complex and highly variable product meets high production volumes.
Drawing from the experiences made in an ongoing real world project for a major car manufacturer, Andreas will provide an in-depth view how Apache Solr and Apache Spark were used to power an innovative architecture that provides lightning-fast BOM explosions, demand forecasts and scenario-based planning on 20 billion records per scenario.

Introducing Datasets: Bringing Compile Time Type Checking and Functional Transformations to Spark DataFrames - Holden Karau, IBM
Apache Spark is a fast and general engine for distributed computing & big data processing with APIs in Scala, Java, Python, and R. DataFrames are a key part of the Spark SQL interface, allowing for relational style transformations and additional optimizations over Spark’s RDDs. Datasets bring much of the power, and compile time type checking, to Spark SQL allowing more developers to benefit from the Catalyst optimizer.

DataFrames allow developers in Apache Spark to access the power of the Catalyst optimizer while continuing to write Scala/Java/Python code. Datasets offer the ability for developers to easily write functional style transformations while still taking advantage of the Catalyst optimizer, compact bit level representation, and so on. Datasets are new in Spark 1.6 and the API will be changing in future versions. This talk will introduce and contrast the APIs.

Time Series Processing with Apache Spark - Josef Adersberger, QAware GmbH
A lot of data is best represented as time series: Operational data, financial data and even in general-purpose DWHs the dominant dimension is time. The area of time series databases is growing rapidly but the support in Spark to process and analyze time series data is still in the early stages. We present Chronix Spark which provides a mature TimeSeriesRDD implementation for fast retrieval and complex analysis of time series data. Chronix Spark is open source software and battle-proved at a big german car manufacturer and a german telco. We show how we‘ve used Chronix Spark in a real-life project and provide some benchmarks how it has outperformed common time series databases like OpenTSDB, KairosDB and InfluxDB. We lift the curtain and deep-dive into the internals how we‘ve achieved this.

Secure Spark Shuffle: A Fast and Convenient Approach Using Chimera - Cheng Xu, Intel
Shuffle is the key process in Spark computing model. It’s very sensitive to performance. Since the frequent crimes and accidents arising from security, data encryption becomes more and more important for an enterprise ready product. In this talk, we will talk about how we use Chimera to secure the shuffle data. Chimera is a cryptography library optimized with AES-NI (Advanced Encryption Standard New Instructions). It provides Java API for both cipher level and Java stream level. It originates from Intel Diceros and Hadoop encryption at rest. It limits the performance impacts using hardware acceleration and helps users get rid of native issues used by native code. In this presentation, we will also show the performance results after enabling the shuffle encryption in Spark.
