> 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).
