Varun Saxena commented on YARN-6197:
------------------------------------
Thanks [~bibinchundatt] for raising the JIRA.
Agree with you that AM usage should not be increased for unmanaged AM. We wont
know where it is launched and how much resources it will use either.
We can check the unmanaged am flag in Scheduler Application Attempt to find out
if its an unmanaged app or not.
> CS Leaf queue am usage gets updated for unmanaged AM

> {{LeafQueue#activateApplication()}} for unmanaged AM the am_usage is updated
> with scheduler minimum allocation size. Cluster resource/AM limit headroom
> for other apps in queue will get reduced .
> Solution: FicaScheduler unManagedAM flag can be used to check AM type.
> Based on flag the queueusage need to be updated during activation and removal
> Thoughts??
