Sandy Ryza commented on YARN-1288:
----------------------------------
For the record, the old default behavior was that the root queue would have
ACLs that defaulted to nobody and all other queues would default to everybody.
The patch switches this, so now the root queue defaults to everybody and all
other queues default to nobody.
> Make Fair Scheduler ACLs more user friendly

> Affects Versions: 2.2.0

> 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.
