Daniele Venzano 591c5eb1ee Add Spark plugin to Sahara 
Integrate the Spark plugin in Sahara. It adds the capability of
provisioning Spark clusters with (Cloudera) HDFS. The plugin
assumes the use of VM images generated with the Savanna
diskimage-builder and the '-p spark' option.

Implements: blueprint spark-plugin

Apache Spark and HDFS Configurations for Sahara

This directory contains default XML configuration files and Spark scripts:

  • core-default.xml,
  • hdfs-default.xml,
  • spark-env.sh.template,
  • topology.sh

These files are used by Sahara's plugin for Apache Spark and Cloudera HDFS. XML config files were taken from here: * https://github.com/apache/hadoop-common/blob/release-1.2.1/src/core/core-default.xml * https://github.com/apache/hadoop-common/blob/release-1.2.1/src/hdfs/hdfs-default.xml

Cloudera packages use the same configuration files as standard Apache Hadoop.

XML configs are used to expose default Hadoop configurations to the users through Sahara's REST API. It allows users to override some config values which will be pushed to the provisioned VMs running Hadoop services as part of appropriate xml config.
