Apache Spark and CERN Open Data Analysis, an Example

Submitted by canali on Tue, 08/29/2017 - 14:01

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.

Integrating Hadoop and Elasticsearch – Part 2 – Writing to and Querying Elasticsearch from Apache Spark

Submitted by pkothuri on Tue, 05/24/2016 - 15:27

Introduction

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.
