Subject [jira] [Commented] (YARN-6727) Improve getQueueUserAcls API to query for specific queue and user
Date Sat, 24 Jun 2017 17:25:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6727?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16062071#comment-16062071

Naganarasimha G R commented on YARN-6727:

Thanks [~bibinchundatt] for the WIP patch.
          As i understand, there are 2 issues currently for large queues
# Amount of data which gets transferred 
# number of computations done in the server side as for each queue we are trying to match
whether user or his group has rights. And also it would suffice to know in most case for the
leaf queue only.

So IIUC your patch is solving only the first part. But for the second one though its not too
much of overhead as no locks are held but its unnecessary computation. So would it better
to optimize it with additional scheduler API too, thoughts ?
Further i was thinking it would be good to have list of queues rather than a single queue.

> 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.
