Rohith Sharma K S commented on YARN-5333:
-----------------------------------------
I think for fixing this issue, for any transistionToActive from admin service,
refreshAll call first. Other things to consider is, skip RM state check only
for transistionToActive nevertheless who calls either admin or elector service.
It guaranty that transitioned RM is always started with new configurations.
Thoughts?

> 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*.
