-------------------------------
HI [~leftnoteasy]
Thanks for the comments. I will work on tests/findbugs/ and comments.
In general I have one doubt below point.
bq.Instead of call methods of appPriorityAclManager (I prefer to remove it, see
#1). Can we call scheduler#checkAndGetApplicationPriority to achieve the same
goal?
I think with {{QueueACLsManager}}, we took ACLs out of CS and managed
externally. Yes, it was to plugin external ACLs policies, however I thought it
was good. I think that was the reason I went with a PriorityACLManager model.
Do you see adding PrioirtyACLs back to scheduler is better? If so, as suggested
we can leverage from scheduler apis. Thoughts?

> Support will be added for User-level access permission to use different
> application-priorities. This is to avoid situations where all users try
> running max priority in the cluster and thus degrading the value of
> priorities.
> Access Control Lists can be set per priority level within each queue. Below
> is an example configuration that can be added in capacity scheduler
> configuration
