> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacity scheduler, resourcemanager
> Affects Versions: 2.8.0

>
> After a reservation queue is allocated, and the plan is synchronized by the plan follower, we expect the user am resource limit to reflect this change if the appropriate configuration is set.
> Instead, the user am resource limit is always the same. As a result, multiple AM cannot run in parallel for small reservations.
> To reproduce this issue, create a reservation, and submit multiple applications against the new reservation.
