> 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,
> {{yarn.scheduler.fair.allow-undeclared-pools}} is set to false,
> {{yarn.scheduler.fair.user-as-default-queue}} is set to false.
> 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 put recovered apps into default queue 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 also important for
> other scheduler*.
