> 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).
