Subject Re: Queue ACLs overridden by yarn.admin.acl
Date Fri, 01 Jul 2016 10:06:48 GMT
Thanks Sunil. Yes, it would be nice to have acl_view_applications on queue
similar to acl_administer_queue. A user can kill other user's job with
acl_administer_queue. Similarly, a user can be made to view other user's
job with acl_view_applications.
