>
> 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).
