Apache Spark Cluster (RStudio stack)


Apache Spark is a fast and general-purpose cluster computing system. It provides high-level APIs in Java, Scala, Python and R, and an optimized engine that supports general execution graphs. It also supports a rich set of higher-level tools including Spark SQL for SQL and structured data processing, MLlib for machine learning, GraphX for graph processing, and Spark Streaming.

Apache Spark cluster together with HDFS (Hadoop Distributed File System) represents one of the most important tool for Big Data and machine learning applications, enabling the parallel processing of large data sets on many virtual machines, which are running Spark workers. On the other hand, setting up a Spark cluster with HDFS on clouds is not straightforward, requiring deep knowledge of both cloud and Apache Spark architecture. To save this hard work for scientists we have created and made public the required infrastructure descriptors by which Occopus can automatically deploy Spark clusters with the number of workers specified by the user. One of the most typical application area of Big Data technology is the statistical data processing that is usually done by the programming language R. In order to facilitate the work of statisticians using Spark on cloud, we have created an extended version of the Spark infrastructure descriptors placing the sparklyr library on Spark workers, too. Finally, we have also integrated the user-friendly RStudio user interface into the Spark system. As a result, researchers using the statistical R package can easily and quickly deploy a complete R-oriented Spark cluster on clouds containing the following components: RStudio, R, sparklyr, Spark and HDFS.

This tutorial sets up a complete Apache Spark infrastructure integrated with HDFS, R, RStudio and sparklyr. It contains a Spark Master node and Spark Worker nodes, which can be scaled up or down.
