> Queue setup: root.family.parent.child[1-2]
> Max res has been set on parent queue. Say, 10GB. Usage is slightly lesser. Say, 9GB. Ask1 (say, 2 GB) had come in for Child1 Queue whose usage is already lesser than its guaranteed quota. So there is a need for preemption. In this case, fence selection/queue selection should not go outside the parent queue hierarchy and queues in the same level as parent (parent queue's siblings) should not be considered at all as accommodating the ask somewhere in parent siblings hierarchy would violate the max resource quota of parent queue.
