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.

> {{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??
