Wangda Tan commented on YARN-7473:
----------------------------------
Thanks [~suma.shivaprasad], comments:
validateAndApplyQueueManagementChanges:
1) Should be part of ManagedParentQueue instead of CS.
2) Instead of using QueueEntitlement, can we use LeafQueueTemplate and
reinitialize LeafQueue?
getInitialEntitlement
1) ordering looks wrong:
2) getInitialEntitlement should be getInitialQueueTemplate and merged to queue
creation path.
commitQueueManagementChanges:
1) Should it part of ManagedParentQueue?
AutoCreatedQueueManagementPolicy#addChildQueue/removeChildQueue:
1) Can we just let policy pull child queues info from parent queue reference?
AutoCreatedQueueManagementPolicy#reinitialize not being used.
AutoCreatedQueueManagementPolicy#init, clock can be removed from parameter list.

> Project: Hadoop YARN
> Issue Type: Sub-task

> This jira mainly addresses the following
>
> 1.Support adding pluggable policies on parent queue for dynamically managing
> capacity/state for leaf queues.
> 2. Implement a default policy that manages capacity based on pending
> applications and either grants guaranteed or zero capacity to queues based on
> parent's available guaranteed capacity.
> 3. Integrate with SchedulingEditPolicy framework to trigger this periodically
> and signal scheduler to take necessary actions for capacity/queue management.
