             Summary: RM should honor NM heartbeat expiry after RM restart
                 Key: YARN-2047
                 URL: https://issues.apache.org/jira/browse/YARN-2047
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Bikas Saha


After the RM restarts, it forgets about existing NM's (and their potentially 
decommissioned status too). After restart, the RM cannot maintain the contract 
to the AM's that a lost NM's containers will be marked finished within the 
expiry time.
