Daniel Templeton created YARN-4373:
--------------------------------------

             Summary: Jobs can be temporarily forgotten during recovery
                 Key: YARN-4373
                 URL: https://issues.apache.org/jira/browse/YARN-4373
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.7.1
            Reporter: Daniel Templeton
            Assignee: Daniel Templeton
            Priority: Critical


The RM becomes available to service requests before state store recovery is started.  Before
recovery and during the recovery period, it's possible for a client to request an application
report for a running application to which the RM will respond that the application in unknown.

I'm seeing this issue with Oozie during an RM failover.  Until the active finishes recovery,
it reports erroneous information to Oozie, which doesn't have context to know that it should
just try again later.
