Robert Kanter commented on OOZIE-1118:
--------------------------------------
I believe that WFs already have a property called "parent" that has the ID of
the COORD that launched it. I don't think COORDs have a similar property for
the ID of the BUNDLE that launched them though.
> improve logic of purge service

> Key: OOZIE-1118
> URL: https://issues.apache.org/jira/browse/OOZIE-1118
> Project: Oozie
> Issue Type: Bug
> Components: bundle, coordinator, workflow
> Affects Versions: 3.3.0
> Reporter: Alejandro Abdelnur
>
> The current logic of the purge service is flat. I.e., WF purging only takes
> into account WF end time, it does not take into account that the WF was
> started by a COORD job. This means that completed WFs of a running COORD job
> could be purge if the COORD job runs for longer that the purge age.
> One way of addressing this would be:
> * WF purging only purges WF jobs started directly by a client call.
> * COORD purging purges COORD jobs started directly by a client call. It also
> purges the WF jobs created by the COORD jobs being purged.
> * BUNDLE purging purges BUNDLE jobs, and the corresponding COORD jobs and WF
> jobs.
> This could be handled by a new property in the job beans 'job-owner'. Set to
> 'self' it would mean it can be purged by the same job type purger. If set to
> other value, then it is a higher level purger the one responsible for purging
> it.
> This means that for a WF job started by COORD job started by a BUNDLE job,
> the WF job and the COORD job would have the BUNDLE job as owner, while the
> BUNDLE with have 'self' as owner.
> This ownership propagation would also have
> A caveat here would be how to handle sub-workflows.
> I guess we should check if the wf was created from coord, and if then let
> the coord purge take care of that, meaning wf purge does not purge wf started
> by coords.
> Similarly, the same should also apply for sub-WFs.
