Ajay Yadava commented on FALCON-1231:
-------------------------------------
[~yzheng-hortonworks]
JMS notifications are slightly better approach in my opinion. They are more
resilient than HTTP notification, even though there are retries for HTTP
notifications. They are also slightly cleaner approach when we want multiple
consumers for the same notifications. My 2 cents.

> URL: https://issues.apache.org/jira/browse/FALCON-1231
> Project: Falcon
> Issue Type: Sub-task

>
> Workflow completion is currently dependent on post processing action putting
> messages (success/failure) to a JMS queue.
> When failures occur on Hadoop / Oozie, the post processing action may not
> get executed either. In such cases, Falcon will be blind to the status of the
> workflow and re-tries will not happen.
> Explore url notification of oozie to get job completion notifications. Fall
> back on polling when workflows run beyond SLA.
