    Description

      Faced some issues while running ATSv2 in single node Hadoop cluster and in the same node had launched Hbase with embedded zookeeper.

      1. Due to some NPE issues i was able to see NM was trying to shutdown, but the NM daemon process was not completed due to the locks.
      2. Got some exception related to Hbase after application finished execution successfully.
        will attach logs and the trace for the same
