spark
Installs Spark on Ubuntu. Requires Hadoop (currently from CDH distribution).
This element will install Spark into an Ubuntu image. It tries to
guess the correct file to download based on the
DIB_SPARK_VERSION
and DIB_CDH_VERSION
variables, 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.
