    Description

      As described in MAPREDUCE-5501 sometimes M/R tests leave MRAppMaster java processes living for several minutes after successful completion of the corresponding test. There is a concurrency issue in MiniYARNCluster shutdown logic which leads to this. Sometimes RM stops before an app master sends it's last report, and then the app master keeps retrying for >6 minutes. In some cases it leads to failures in subsequent tests, and it affects performance of tests as app masters eat resources.
