Subject [jira] [Commented] (MAPREDUCE-3028) Support job end notification in .next /0.23
Date Tue, 18 Oct 2011 15:17:11 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3028?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13129789#comment-13129789

Vinod Kumar Vavilapalli commented on MAPREDUCE-3028:
----------------------------------------------------

No, I'd not put this in YARN (i.e Nodemanager). The notification is currently a MapReduce
only feature (atleast it seems to be for now). I can imagine a generic application finish
notification from YARN itself (RM or NM), but I'd postpone any discussion about that if we
can pull it off in MapReduce AM for now.

Also 30secs seems way too much, even if it for that one job. Make it something in the order
of 5s of seconds?

> 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.
