> Several fixes:
> 1. Set YARN_FAIL_FAST to be false by default, since this makes more sense in production
environment.
> 2. If HA is enabled and if there's any state-store error, after the retry operation failed,
we always transition RM to standby state.  Otherwise, we may see two active RMs running. YARN-4107
is one example.
