>                 Key: YARN-5333
>                 URL: https://issues.apache.org/jira/browse/YARN-5333
>             Project: Hadoop YARN
>          Issue Type: Bug
>            Reporter: Jun Gong
>            Assignee: Jun Gong

> Enable RM HA and use FairScheduler.
> Reproduce steps:
> 1. Start two RMs.
> 2. After RMs are running, change both RM's file {{etc/hadoop/fair-scheduler.xml}}, then
add some queues.
> 3. Submit some apps to the new added queues.
> 4. Stop the active RM, then the standby RM will transit to active and recover apps.
> However the new active RM will reject recovered apps because it might have not loaded
the new {{fair-scheduler.xml}}. We need call {{initScheduler}} before start active services
or bring {{refreshAll()}} in front of {{rm.transitionToActive()}}. *It seems it is aslo important
for other scheduler*.
