Subject [jira] [Commented] (YARN-899) Get queue administration ACLs working
Date Wed, 07 Aug 2013 16:44:50 GMT

    [ https://issues.apache.org/jira/browse/YARN-899?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13732148#comment-13732148

Xuan Gong commented on YARN-899:
--------------------------------

Thanks for the comments. Sandy.

bq.We should go with an approach that generalizes for all schedulers.

Yes, we should do that. How about using a more generalized type : Queue. Looks like that Queue
is the super type for all the csqueue, FSQueue, and queue used in all three schedulers.

bq.Queue submission ACLs are enforced internally by the schedulers on addApplication. Would
it make sense to use a similar approach with removeApplication? If not, the submission ACLs
should probably be modified to use whatever mechanism is added.

We can do that

bq.In MR1, did the administer ACLs control who could view jobs in a queue? My impression was
that they only controlled who could kill jobs and change their priorities.

Yes, based on the documentation, it shows "queue administrators of the queue to which the
job was submitted to (mapred.queue.queue-name.acl-administer-jobs) always have access to view
and modify a job ".

> 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.
