> When RM state store entered an unexpected state, one example is YARN-2340,
> when an attempt is not in final state but app already completed, RM can never
> get up unless format RMStateStore.
> I think we should support remove individual application records from
> RMStateStore to unblock RM admin make choice of either waiting for a fix or
> format state store.
> In addition, RM should be able to report all fatal errors (which will
> shutdown RM) when doing app recovery, this can save admin some time to remove
> apps in bad state.
