> 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.
