Bilwa S T updated YARN-11181:
-----------------------------
Description:
Configure two queues q1 and q2.
Lets say AM Resource percent for q1 and q2 is both <5gb, 5vcores>.
1. Run long running application to q1 which occupies 70% of cluster resources
2. Run small application to q2 .
3. Run one long running job to q2 and few more small jobs.
4. Once small application submitted to q2 finishes , AM resources gets
decreased to <2gb, 2vcores>
5. Kill long running application submitted to q1.
Now long running job submitted to q2 will be running and all other jobs are in
pending state.
This is because LeafQueue#ActivateApplications gets called only when AM starts
running or finishes.
> Applications in Pending state as AM resources are not updated when resources
> from other queue gets released
