Major Description
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.
