Zhijie Shen commented on YARN-1430:
-----------------------------------
Personally, I think ignoring InvalidStateTransition is not bad idea, though it
may hide some existing bugs from us. However, it particularly results in
isolation, preventing RM/NM from be crashed by a single race condition. To be
more accurate, if InvalidStateTransition happens to one application, this
application will not be completed, crash or anything, while other applications
that are running simultaneously should not be affected.
> InvalidStateTransition exceptions are ignored in state machines

> We have all state machines ignoring InvalidStateTransitions. These exceptions
> will get logged but will not crash the RM / NM. We definitely should crash it
> as they move the system into some invalid / unacceptable state.
> * Places where we hide this exception :-
> ** JobImpl
> ** TaskAttemptImpl
> ** TaskImpl
> ** NMClientAsyncImpl
> ** ApplicationImpl
> ** ContainerImpl
> ** LocalizedResource
> ** RMAppAttemptImpl
> ** RMAppImpl
> ** RMContainerImpl
> ** RMNodeImpl
> thoughts?
