Karthik Kambatla commented on YARN-6061:
----------------------------------------
Now I know why my perception of reality is different from reality. YARN-2579
has moved transitioning the RM to standby from RMFatalEventDispatcher to
RMStateStore to avoid a deadlock in the RM.
Can we have RMCriticalThreadUncaughtExceptionHandler mimic the same behavior?
Maybe, share StandByTransitionThread?

> There are several threads in fair scheduler. The thread will quit when there
> is a runtime exception inside it. We should bring down the RM when that
> happens. Otherwise, there may be some weird behavior in RM.
