      Description

      In YARN UI, the MapReduce application state is marked as FINISHED, however java process corresponding to the MRAppMaster(container 01) still keeps running for around 10 more minutes. This delays freeing of the cluster resources which are acquired by MRAppMaster.

      I could not reproduce the same issue for Spark.
