Wangda Tan commented on YARN-7473:
----------------------------------
Thanks [~suma.shivaprasad], for updating the patch.
I suggest to revert this part:
{code}
198
199 //If absolute capacity is 0 for a leaf queue (could be a managed
leaf
200 // queue, then use the leaf queue's template capacity to compute
201 // guaranteed resource for used capacity)
202 float absoluteCapacity = queueCapacities.getAbsoluteCapacity
203 (nodePartition);
204 if (Float.compare(absoluteCapacity,
205 0f) == 0 && childQueue instanceof AutoCreatedLeafQueue) {
206 ManagedParentQueue parentQueue = (ManagedParentQueue)
207 childQueue.getParent();
208 QueueCapacities leafQueueCapacities =
parentQueue.getLeafQueueTemplate()
209 .getQueueCapacities();
210 absoluteCapacity = leafQueueCapacities.getAbsoluteCapacity
211 (nodePartition);
212 }
{code}.
Other than that, patch looks good, could you take care of
findbugs/checkstyle/unit test issues?

> 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.
