-------------------------------

             Summary: When RM is catching up with node updates then it should not expire acquired containers
                 Key: YARN-433
                 URL: https://issues.apache.org/jira/browse/YARN-433
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Bikas Saha
            Assignee: Xuan Gong


RM expires containers that are not launched within some time of being allocated. The default is 10mins. When an RM is not keeping up with node updates then it may not be aware of new launched containers. If the expire thread fires for such containers then the RM can expire them even though they may have launched.
