--------------------------------------
Summary: Picking Victims should consider usage and max quota for
queues at each level
Key: YUNIKORN-2507
URL: https://issues.apache.org/jira/browse/YUNIKORN-2507
Project: Apache YuniKorn
Issue Type: Sub-task
Components: core - scheduler
Reporter: Manikandan R
Assignee: Manikandan R
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
greater than its guaranteed quota (borrowed by some other child queues). 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.
