Description

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.
