Subject [jira] [Commented] (YARN-899) Get queue administration ACLs working
Date Wed, 07 Aug 2013 19:27:52 GMT

    [ https://issues.apache.org/jira/browse/YARN-899?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13732615#comment-13732615
] 

Sandy Ryza commented on YARN-899:
---------------------------------

bq. In case of YARN, a queue is a YARN construct. Queue acls should be enforced by YARN and
not by each scheduler.
Agreed.  We will need to change this for the existing submit ACLs as well.  Currently the
scheduler holds which applications are in which queues and the ACLs for each queue.  I don't
think we should change that part, so perhaps an interface like Scheduler#getQueueACLs(ApplicationAttemptId)
would make sense?

bq. There are separate acls for who can view as compared to who can modify ( kill, etc ).
As far as I can tell this is not how it worked for queue ACLs in MR1, but I think this is
how we should do it for MR2.

> The Capacity Scheduler documents the yarn.scheduler.capacity.root.<queue-path>.acl_administer_queue
config option for controlling who can administer a queue, but it is not hooked up to anything.
 The Fair Scheduler could make use of a similar option as well.  This is a feature-parity
regression from MR1.
