bq. I think it is safe to check that the event types are ones we are interested in.
done.

bq. In JobQueueManager, I am thinking if it's a good idea to retain the implementation in
jobRemoved just in case.
Keeping {{jobRemoved}} might mask some errors if any as we are sure that the job should be
removed upon job completion.

bq. I couldn't find a test case that tests priority changes are handled correctly. Is this
added ?
Added now.

> The JobInProgressListener interface is used by the framework to notify Schedulers of
when jobs are added, removed, or updated. Right now, there is no way for the Scheduler to
know that a job has completed. jobRemoved() is called when a job is retired, which can happen
many hours after a job is actually completed. jobUpdated() is called when a job's priority
is changed. We need to notify a listener when a job has completed (either successfully, or
has failed or been killed).
