This is a short post introducing a notebook that you can use to play with a simple analysis of High Energy Physics (HEP) data using CERN open data and Apache Spark. The idea for this work started with a concept for a technology demonstrator of some recent developments on using Spark for data analysis in the context of HEP.
Alluxio refers to itself as an "Open Source Memory Speed Virtual Distributed Storage" platform. It sits between the storage and processing framework layers in the distributed computing ecosystem and claims to heavily improve performance when multiple jobs are reading/writing from/to the same data. This post will cover some of the basic features of Alluxio and will compare its performance for accessing data against caching in Spark.
In the part 2 of 'Integrating Hadoop and Elasticsearch' blogpost series we look at bridging Apache Spark and Elasticsearch. I assume that you have access to Hadoop and Elasticsearch clusters and you are faced with the challenge of bridging these two distributed systems. As spark code can be written in scala, python and java, we look at the setup, configuration and code snippets across all these three languages both in batch and interactively.
