> 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.
