kyungwan nam commented on YARN-8095:
------------------------------------

I attached a patch, which respect the accessible-node-lables even though 
non-exclusive allocation.

when the capacity-scheduler configs are as follows
{code:java}
yarn.scheduler.capacity.root.batch.accessible-node-labels=label1
yarn.scheduler.capacity.root.longlived.accessible-node-labels= {code}
I’ve seen that apps submitted to root.longlived does not allocated on ‘label1’ 
partition. 

> Allow disable non-exclusive allocation

>    Affects Versions: 2.8.3

> We have 'longlived' Queue, which is used for long-lived apps.
> In situation where default Partition resources are not enough, containers for 
> long-lived app can be allocated to sharable Partition.
> Since then, containers for long-lived app can be easily preempted.
> We don’t want long-lived apps to be killed abruptly.
> Currently, non-exclusive allocation can happen regardless of whether the 
> queue is accessible to the sharable Partition.
> It would be good if non-exclusive allocation can be disabled at queue level.
