Purshotam Shah commented on OOZIE-2647:
---------------------------------------

True, your start instance is {{startTime}} and job start time is also {{startTime}}. So for 1st action, current(-1) is nothing. You should move back your dataset start-instance with one dataset frequency.

> Hi,
> We've noticed that if you have a definition like this in the coordinator.xml, then the first action is always released and the existence of the data dependency is never checked/verified. This only seems to happen with the value "-1" and nothing else ("0", any other positive or negative value seems to be fine).
> I currently don't have access to a more recent release, but I also couldn't locate a bug related to this in here.
