Shwetha G S commented on OOZIE-1536:
------------------------------------
Current behaviour is that a re-run of a coord action submits a new workflow. So
now there are two workflows in oozie for the same nominal time of that coord.
Externally, the user can re-run these workflows independently and it will
result in random outputs depending on the order of execution as they share the
same output path.
Also, if a workflow has a sub workflow, re-run of this workflow launches a new
workflow for the sub-workflow.
Instead, if the coord action re-run just re-runs the existing workflow, there
can be just 1 instance that is running for a nominal time of a coord and
doesn't cause any issues. Even sub-workflow re-run should re-run the existing
workflow itself. This also helps to decrease the ooziedb size.

> Coordinator action reruns start a new workflow and if existing workflow for
> the action is in running state, the same is not checked. Coord rerun can
> possibly do a workflow re-run to prevent this.
