------------------------------------
Hi Robert,
I'll need to sanitize the workflows and probably won't be able to do that till
sometime next week. That being said, I do indeed have forks/joins within the
workflow. However they are logically separated in the DAG from the scenarios
that I listed as having problems with.
This is the full exception I'm getting (not very useful I'm afraid, as I
couldn't find a corresponding stacktrace in the logs):
OozieClientException: org.apache.oozie.DagEngineException: E0743: Multiple "ok
to" transitions to the same node, [oldDatasetDelete], are not allowed
> forkjoin validation blocks some valid cases involving decision nodes

> in OOZIE-1035, the new forkjoin checker code is blocking some valid cases
> involving decision nodes.
> 1) This uses a decision node to "insert" an action based on {{foo}}:
> {noformat}
> <decision>
> <if foo, goto action A>
> <else, goto action B>
> </decision>
> <action A>
> <ok to="B">
> </action A>
> <action B>
> </action B>
> {noformat}
> 2) This uses a decision node to "replace" an action based on {{foo}}:
> {noformat}
> <decision>
> <if foo, goto A>
> <else, goto B>
> </decision>
> <action A>
> <ok to C>
> </action A>
> <action B>
> <ok to C>
> </action B>
> {noformat}
