Subject [jira] [Commented] (FALCON-1313) Generate notification for Falcon job status
Date Fri, 17 Jul 2015 09:19:04 GMT

    [ https://issues.apache.org/jira/browse/FALCON-1313?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14631080#comment-14631080

Pallavi Rao commented on FALCON-1313:
-------------------------------------

[~peeyushb], the primary problem with any notification from Falcon is that it will not be
reliable. Users would generally want to know when there are failures (rather than success).
And, in case of failures, the notification may not get generated at all (either via oozie)
or for that matter via JMS notifications. 

If you add the email notification as part of post-process, the user action may succeed, but,
post-process may fail. 
If you listen to JMS notifications that are generated now, even there, JMS notifications may
not generated because the post-processing failed.

So, at best, what we are guaranteeing is SUCCESS notifications in case of "Success" which
can be achieved using oozie email action. But, lack of notification, MAY, but not necessarily
(when post-processing fails), mean a failure.

I think we need to be able to reliably determine the status of a workflow/action before we
bring in this feature.

job finish either with success/failure.
