Sandy Ryza commented on YARN-1288:
----------------------------------
bq. Would this be an incompatible change? If so, can the configuration be set
to have the previous behavior? If so, that should be the default setting.
Yes it is an incompatible change. The commit concerns the default settings and
thus we can't leave the previous behavior, which is incorrect, as the default.
bq. Documentation is missing.
Will add some doc

> Key: YARN-1288
> URL: https://issues.apache.org/jira/browse/YARN-1288
> Project: Hadoop YARN
> Issue Type: Bug
> Components: scheduler
> 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.
