[jira] [Created] (YARN-3987) am container complete msg ack to NM once RM receive it

sandflee created YARN-3987:
------------------------------

             Summary: am container complete msg ack to NM once RM receive it
                 Key: YARN-3987
                 URL: https://issues.apache.org/jira/browse/YARN-3987
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
            Reporter: sandflee


In our cluster we set max-am-attempts to a very very large num, and unfortunately our am crash after launched, leaving too many completed container(AM container) in NM.  completed container is removed from NM and NMStateStore only if container complete is passed to AM, but if AM couldn't be launched, the completed AM container couldn't be cleaned, and may eat up  NM heap memory.
