>                 Key: YARN-4087
>                 URL: https://issues.apache.org/jira/browse/YARN-4087
>             Project: Hadoop YARN
>          Issue Type: Bug
>            Reporter: Jian He
>            Assignee: Jian He
>         Attachments: YARN-4087.1.patch, YARN-4087.2.patch, YARN-4087.3.patch
> Several fixes:
> 1. Set YARN_FAIL_FAST to be false by default, since this makes more sense in 
> production environment.
> 2. Fixe state-store to also notify app/attempt if state-store error is 
> ignored so that app/attempt is not stuck at *_SAVING state
> 3. 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.
