[jira] [Created] (MAPREDUCE-4421) Remove dependency on deployed MR jars

Arun C Murthy created MAPREDUCE-4421:
----------------------------------------

             Summary: Remove dependency on deployed MR jars
                 Key: MAPREDUCE-4421
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4421
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
    Affects Versions: 2.0.0-alpha
            Reporter: Arun C Murthy


Currently MR AM depends on MR jars being deployed on all nodes via implicit dependency on YARN_APPLICATION_CLASSPATH. 

We should stop adding mapreduce jars to YARN_APPLICATION_CLASSPATH and, probably, just rely on adding a shaded MR jar along with job.jar to the dist-cache.
