Subject [jira] [Created] (YARN-6168) Restarted RM may not inform AM about all existing containers

Billie Rinaldi created YARN-6168:
------------------------------------

             Summary: Restarted RM may not inform AM about all existing containers
                 Key: YARN-6168
                 URL: https://issues.apache.org/jira/browse/YARN-6168
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Billie Rinaldi


There appears to be a race condition when an RM is restarted. I had a situation where the
RMs and AM were down, but NMs and app containers were still running. When I restarted the
RM, the AM restarted, registered with the RM, and received its list of existing containers
before the NMs had reported all of their containers to the RM. The AM was only told about
some of the app's existing containers.
