Carlo Curino commented on YARN-6234:
------------------------------------
Per offline discussion with [~subru]:
The two cases (1,2) above can be handled uniformly by YARN-6128, but we can add
later on some more efficient caching of {{AMRMToken}} for the (1) case. Please
address the comments from duplicate, ok to postpone (1).
> Support multiple attempts on the node when AMRMProxy is enabled

> Currently {{AMRMProxy}} initializes an interceptor chain pipeline for every
> active AM in the node but it doesn't clean up & reinitialize correctly if
> there's a second attempt for any AM in the same node. This jira is to track
> the changes required to support multiple attempts on the node when AMRMProxy
> is enabled.
