>                 URL: https://issues.apache.org/jira/browse/YARN-4087
>             Project: Hadoop YARN
>          Issue Type: Bug
>            Reporter: Jian He
>            Assignee: Jian He
>             Fix For: 2.7.2, 2.6.2
>
>         Attachments: YARN-4087-branch-2.6.patch, YARN-4087.1.patch, YARN-4087.2.patch,
YARN-4087.3.patch, YARN-4087.5.patch, YARN-4087.6.patch, YARN-4087.7.patch
>

> 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.
