%description 
Spark is a MapReduce-like cluster computing framework designed to support
low-latency iterative jobs and interactive use from an interpreter. It is
written in Scala, a high-level language for the JVM, and exposes a clean
language-integrated syntax that makes it easy to write parallel jobs.
Spark runs on top of the Apache Mesos cluster manager.
