-----------------------------------------------

This seems a dup of MAPREDUCE-3428 (if so please close one of them)

> The CLASSPATH for the MapReduce Application master is set using compile time path information,
which is typically different from run-time. This will cause failure when running on different
environments.
> Specifically, the YarnRunner, and as part ApplicationSubmissionContext creation, sets
the classpath for the application master using MRApps.setClasspath(environment), and then
the setMRFrameworkClasspath(..) method uses compile time path information present in the "mrapp-generated-classpath"
file (created at compile-time).
