Subject [jira] [Commented] (MAPREDUCE-3028) Support job end notification in .next /0.23
Date Fri, 21 Oct 2011 17:24:33 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3028?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13132844#comment-13132844

Mahadev konar commented on MAPREDUCE-3028:
------------------------------------------

Wait,
 I take that back, looks like in MRJobConfig:

END_NOTIFICATION_URL  -> MR_JOB_END_NOTIFICATION_URLS
and
mapreduce.job.end-notification.url ->mapreduce.job.end-notification.urls

So doesnt look like they wont require any change. We should probably keep this consistent
so that downstream projects using it do not break.

> 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.
