SAGA Hadoop

Last Updated: 12/09/2017

Overview:

Use SAGA to spawn an Hadoop Cluster within an HPC batch job.

Currently supported SAGA adaptors:

  • Fork
  • Torque

Requirements:

* PBS/Torque cluster
* Working directory should be on a shared filesystem
* Setup password-less documentation
* JAVA needs to be installed and in PATH

By default SAGA-Hadoop deploys an Hadoop 2.2.0 YARN cluster. The cluster can be customized by adjusting the templates for the Hadoop configuration files in core-site.xml, hdfs-site.xml, mapred-site.xml and yarn-site.xml in the hadoop2/bootstrap_hadoop2.py.

Usage

Requirement:

pip install pykafka saga-python

Try to run a local Hadoop (e.g. for development and testing)

pip install saga-hadoop
saga-hadoop --resource fork://localhost

Try to run a Hadoop cluster inside a PBS/Torque job:

saga-hadoop --resource pbs+ssh://india.futuregrid.org --number_cores 8
