> 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.
