      Description

      We have seen in RM log a lot of

      INFO org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler: Null container completed...

      It is caused by NM sending completed containers repeatedly until the app is finished. On the RM side, the container is already released, hence getRMContainer returns null.
