> Since the CapacityScheduler internal implementation depends more and more on
> queue being hierarchical, the test gets really hard to maintain. A lot of
> test cases were failing because they used non existing queues, but the older
> placement rule solution ignored missing parents, but since the leaf queue
> change in CS, we must be able to get a full path for any queue, since all
> queues are referenced by their full path.
> This test should reflect this and instead of creating and expecting the
> existance of fictional queues, it should create a proper queue hierarchy,
> with a way to describe it better.
> Currently we set up a bunch of mockito "when" statements to simulate the
> queue behavior, but this is a hassle to maintain, and easy to miss a few
> method.
