             Summary: Quota Preemption check quota preemption incorrect victim selection
                 Key: YUNIKORN-3284
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-3284
             Project: Apache YuniKorn
          Issue Type: Task
            Reporter: Aditya Maheshwari
            Assignee: Aditya Maheshwari


Test steps - # Create a queue {{queue-a}} with max resource limit of 300 and submit an application {{app-a}} with 3 pods to this queue. All pods should come up fine.
 # Update quota of queue-a and set max resource to 250 now (from 300 earlier) with delay of 30 seconds and quotaPreemption enabled.
 # Before the delay expires, submit another application {{app-b}} with resource 50 to {{queue-a}} . As expected {{app-b}} becomes pending as the queue is full.
 # After delay expires, preemption triggers, but instead of pod of {{{}app-a{}}}, pod of {{app-b}} is chosen as victim, which is already in pending state. I think this is done because {{app-b}}

is of 50 and the resource went down by 50 (300->250) in step 2.

So step 4 is not working as expected.

In the end all 3 pods of app-a are running consuming 300, and in configs max resource limit is still 250 set from step 2. This is inconsistent step.
