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.
