Varun Saxena commented on YARN-3893:
------------------------------------

[~xgong], issue with reinitialization is that if exception is thrown during 
initialization then all the active services will be stopped. 
And when we transitiontoactive we will directly attempt to start active 
services which would fail because services are in state STOPPED.

I think we can forcibly set the state to standby and set a flag in RMContext 
indicating reinit is required whenever attempting transition to standby or 
active. This way we will let leader election handle the exception.

> Both RM in active state when Admin#transitionToActive failure from refeshAll()
