Arun C Murthy commented on MAPREDUCE-3028:
------------------------------------------
Agreed. Let's keep it simple:
# AM, at the end of the job, tries a small number of times (3/5).
# Each retry has a short, aggressive timeout.
> Support job end notification in .next /0.23

> Oozie primarily depends on the job end notification to determine when the
> job finishes. In the current version, job end notification is implemented in
> job tracker. Since job tracker will be removed in the upcoming hadoop release
> (.next), we wander where this support will move. I think this best effort
> notification could be implemented in the new Application Manager as one of
> the last step of job completion.
> Whatever implementation will it be, Oozie badly needs this feature to be
> continued in next releases as well.
