Robert Kanter commented on OOZIE-1166:
--------------------------------------
Replacing #USER# makes sense; also the hint is a clearer message than what I
had. I'm not sure if an empty doAsUser would be a symptom of this misconfig,
so I'll leave that out. I'll upload a new patch soon.
----
Using a library for arg checking might be a good idea; I've filed OOZIE-1169 to
investigate.
