> 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 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*.
