Wilfred Spiegelenburg resolved YARN-6941.
-----------------------------------------
Resolution: Won't Fix
The XML is already ordered so it does not make sense to override the ordering
which is in the XML.
> Allow Queue placement policies to be ordered by attribute

> Key: YARN-6941
> URL: https://issues.apache.org/jira/browse/YARN-6941
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: fairscheduler
> Reporter: Yufei Gu
> Priority: Minor
>
> It would be nice to add a feature that would allow users to provide an
> "order" or "index" the placement policies should apply, rather than just the
> native policy order as included in the XML.
> For instance, the following two examples would be the same:
> Natural order:
> <queuePlacementPolicy>
> <rule create="false" name="specified"/>
> <rule create="false" name="user"/>
> <rule name="default"/>
> </queuePlacementPolicy>
> Indexed Order:
> <queuePlacementPolicy>
> <rule index="2" name="default"/>
> <rule index="1" create="false" name="user"/>
> <rule index="0" create="false" name="specified"/>
> </queuePlacementPolicy>
