Hemanth Yamijala commented on HADOOP-4053:
------------------------------------------

The {{JobInProgressListener}} states it is for capturing lifecycle of a job. 
Given that, a job's state change when it completes is a lifecycle change. And 
therefore, it should be notified by a separate API such as {{jobCompleted()}}. 
So +1 for that approach.

Since there are schedulers already implemented, should we make this method a 
concrete one in {{JobInProgressListener}} that's a no-op, and allow the 
individual schedulers to override and implement the desired functionality ?

> 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).
