Robert Kanter commented on OOZIE-1195:
--------------------------------------
I can't quite follow what you were doing with the XML; can you re-explain what
the issue is (and also use formatting tags like \{code\} or \{noformat\} to
make the XML and stack trace easier to read)?
Not allowing end nodes in a fork-join path is the correct behavior because an
end node means that the workflow completed successfully, but if its in a
fork-join then the other paths will still be executing actions when we get to
the end node, meaning that those paths didn't actually finish when the workflow
finishes, so its not _right_ to call it a success (I'm not actually sure what
Oozie does if you disable fork-join validation and try this but I'd guess that
it will either kill the other paths, which doesn't sound like a success to me,
or it will keep executing those paths even though the workflow itself has
finished, which isn't good either).
On the other hand, a kill node is allowed because that will cause Oozie to kill
the actions in the other path when it kills the workflow and so there's no
ambiguity here. Does this clarify things?
