Amar Kamat updated HADOOP-4053:
-------------------------------
Attachment: HADOOP-4053-v5.4.patch
With HADOOP-4261, a job moves to {{RUNNING}} state only after the _setup_ tasks
are complete. Hence invoking {{jobUpdated()}} after {{initTasks()}} is useless
as there is no _run-state_ change. Attaching a patch that correctly captures
the run-state changes in a job and informs the listeners about it.
Result of _test-patch_ on my box :
{code}
[exec] +1 overall.
[exec]
[exec] +1 @author. The patch does not contain any @author tags.
[exec]
[exec] +1 tests included. The patch appears to include 9 new or
modified tests.
[exec]
[exec] +1 javadoc. The javadoc tool did not generate any warning
messages.
[exec]
[exec] +1 javac. The applied patch does not increase the total number
of javac compiler warnings.
[exec]
[exec] +1 findbugs. The patch does not introduce any new Findbugs
warnings.
{code}
Testing in progress.

> 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).
