Pallavi Rao commented on FALCON-1231:
-------------------------------------
Per today's discussion, there is an additional requirement to generate
notification when instance goes into "WAITING" state. Based on that, I will
update the patch to notify on "WAITING" and "TIMED_OUT".
For WAITING, I will introduce a new onWaiting() method to the listener
interface.
However, "TIMED_OUT" will generate a FAILURE notification(onFailure()), with
status set to "TIMED_OUT". Basically, classifying any status other than
SUCCESS/SUSPEND as failure.
[~ajayyadava], [~yzheng-hortonworks], does this address your use case?

> 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.
