Sandy Ryza commented on YARN-1288:
----------------------------------
Attached patch that makes the changes discussed above. To avoid allocating and
filling a HashMap every time acls are checked, the patch also changes
QueueManager#getQueueAcls to QueueManager#getQueueAcl and removes the
getQueueAcls method in Queue that is no longer needed because of this.
> Make Fair Scheduler ACLs more user friendly

>
> The Fair Scheduler currently defaults the root queue's acl to empty and all
> other queues' acl to "*". Now that YARN-1258 enables configuring the root
> queue, we should reverse this. This will also bring the Fair Scheduler in
> line with the Capacity Scheduler.
> We should also not trim the acl strings, which makes it impossible to only
> specify groups in an acl.
