Varun Saxena commented on YARN-4000:

I meant in terms starting RM from scratch only. I mean the configuration isnt 
rejected on start(will be rejected on switchover though). So I thought in this 
case, we can fail the currently running apps instead of not letting RM start. 
Anyways fail-fast config seems to be a viable option instead choosing either of 
the approaches.

> 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.
