Steve Loughran commented on HADOOP-4053:
----------------------------------------
Hemanth, why do you want the event classes to be package private? I'm going to
listen to them and then feed the events off to other things that may be
interested. Making them package private forces me to write my classes in the
hadoop package, and prevents me relaying the events to code in different
packages.

> 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).
