Bibin A Chundatt commented on YARN-6727:
----------------------------------------

Thank you [~sunilg] and [[email protected]] for looking into the 
same.
I would like split into two
# precomputed access checks for active/non-active users
# Api Interface change 

lets focus of API interface change in this JIRA and will raise another for 
caching precomputed ACLS

> Improve getQueueUserAcls API to query for  specific queue and user

> Currently {{ApplicationClientProtocol#getQueueUserAcls}} return data for all 
> the queues available in scheduler for user.
> User wants to know whether he has rights of a particular queue only. For 
> systems with 5K queues returning all queues list is not efficient.
> Suggested change: support additional parameters *userName and queueName* as 
> optional. Admin user should be able to query other users ACL for a particular 
> queueName.
