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.

> 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>
