Varun Saxena commented on YARN-4000:
------------------------------------

[~jianhe], moreover there will be subclasses of RMAppEvent which also have their version of diagnostics.
Maybe we would want to refactor that as well. Do it as part of this JIRA only ?

> This is a similar situation to YARN-2308.  If an application is active in queue A and then the RM restarts with a changed capacity scheduler configuration where queue A becomes a parent queue to other subqueues then the RM will crash with a NullPointerException.
