Yufei Gu created YARN-6941:
------------------------------
Summary: 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
Assignee: 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>
