Robert Joseph Evans commented on MAPREDUCE-3028:
------------------------------------------------
The problem with the RSS feed for Oozie is that Oozie wants a push notification
so that it can start other jobs as quickly as possible and avoid polling to
know when a job has finished. Currently it supports polling in addition to the
push but I believe the default polling interval is set to 10 min to reduce the
load on the task tracker.
There also may be other applications that depend on the push notification just
like we had before. So for feature parity we probably still need the end
notification.

> 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.
