Wilfred Spiegelenburg commented on YARN-7562:
---------------------------------------------
I think you are going the wrong direction: this is not a code problem but a
configuration issue. Please read my previous update.
You are still breaking existing configurations and use cases. The
_primaryGroup_ and _secondaryGroupExistingQueue_ can be used as the nested rule
in the _nestedUserQueue_ rule as per the example that we have in the
[documentation|https://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/FairScheduler.html#Automatically_placing_applications_in_queues].
They must be allowed to return a parent queue.
> queuePlacementPolicy should not match parent queue
