Vitaly Gridnev 972ce02c76 Fixing spark and CDH refinements 
Actually there is no much difference between using CDH 5.4 and 5.5
for spark, because both are using Hadoop 2.6 as a base.
Also removing redundant case in installing packages for CDH.

spark

Installs Spark. Requires Hadoop.

This element will install Spark. It tries to guess the correct file to download based on the DIB_SPARK_VERSION and DIB_CDH_VERSION, but this behaviour can be overridden by using SPARK_DOWNLOAD_URL to specify a download URL for a pre-built Spark tar.gz file. See http://spark.apache.org/downloads.html for more download options.

Versions

This element is able to generate images containing any valid Spark version, compiled against one version of Hadoop HDFS libraries.

Only some combinations of Spark and Hadoop versions are possible, depending on the availability of a pre-compiled binary and only few of them are tested with the Sahara Spark plugin.

The diskimage-create.sh script will use tested defaults. Those defaults generate an image supported by the Sahara Spark plugin. Other combinations should be used only for evaluation or testing purposes. Refer to the Sahara Spark plugin wiki page (https://wiki.openstack.org/wiki/Sahara/SparkPlugin) for more information about tested and supported versions.

Environment Variables

DIB_SPARK_VERSION
Required

Yes, if SPARK_DOWNLOAD_URL is not set.

Description

Version of the Spark package to download.

Example

DIB_SPARK_VERSION=1.3.1

DIB_CDH_VERSION
Required

Required only for images for Spark Plugin and if SPARK_DOWNLOAD_URL is not set.

Description

Version of the CDH platform to use for Hadoop compatibility. CDH version 5.3 is known to work well.

Example

DIB_CDH_VERSION=5.3

SPARK_DOWNLOAD_URL
Required

No, if set overrides DIB_CDH_VERSION and DIB_SPARK_VERSION

Description

Download URL of a tgz Spark package to override the automatic selection from the Apache repositories.
