[jira] [Updated] (YARN-5447) Consider including allocationRequestId in NMContainerStatus to allow recovery in case of RM failover

     [ https://issues.apache.org/jira/browse/YARN-5447?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Subru Krishnan updated YARN-5447:
---------------------------------
    Description: We have added a mapping of the allocated container to the original request through YARN-4887/YARN-4888. There is a corner case in which the mapping will be lost, i.e. if RM fails over before notifying the AM about newly allocated container(s). This JIRA tracks the changes required to include the allocationRequestId in NMContainerStatus to allow recovery in case of RM failover.  (was: We have added a mapping of the allocated container to the original request through YARN-4887/YARN-4888. This JIRA tracks the changes required to include the allocationRequestId in NMContainerStatus to allow recovery in case of RM failover.)
