Attachment: HIVE-13599.01.patch
The exception trace itself is not very damaging - this was a result of using an
incorrect method on the queue - remove which throws an Exception, instead of
poll which returns a null. The code following this assumed a null return.
However, there's definitely problems with the way the preemption queue was
being updated in various cases - as Prasanth pointed out - an incorrect type
was being used in one case. Also the isInPreemptionQueue status was not being
updated properly.
The patch fixes this, and adds a couple of unit tests to verify the state of
the preemption queue - including when finishable state changed notifications
are received.
