--------------------------------------------------------------
[~ccondit] can you take a look at [PR 659
|[https://github.com/apache/yunikorn-core/pull/659]] ?
With this change, previous check [currentQueue|#L204]] will not always be true,
which could help the intra-queue preemption issue.
I will update the test shortly in next iteration.

> *Background*
> We noticed preemption happens for jobs within same queue.
>
> *Test we have done*
> * Submitted job1 to root.test-queue.tier1 queue, queue allocated usage went
> higher than guaranteed resource.
> * Then submitted another Job2 to same queue, queue allocated usage decreased
> to lower than guaranteed resource.
> * Most executors of Job1 got preempted by Job2
