MR AppMaster CLASSPATH is dependent on the compile-time environment 
--------------------------------------------------------------------

                 Key: MAPREDUCE-3428
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3428
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 0.23.0
            Reporter: Ahmed Radwan


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 "setMRFrameworkClasspath"
file (created at compile-time).
