Robert Kanter commented on OOZIE-1319:
--------------------------------------
You're right, those two cases will both be problematic. I'm not sure of a good
way to solve them; any ideas?
What if we made it LAST_ONLY a little more restrictive and have it effectively
set the timeout equal to the frequency? I believe this would help prevent the
second case because even if a bunch of data dependencies get satisfied at the
same time, the older actions would have already TIMEDOUT, so you'd only have
the current one.
> "LAST_ONLY" in execution control for coordinator job still runs all the
> actions

> In execute() of CoordJobGetReadyActionsJPAExecutor.java, once we retrieve the
> top item from a "LIFO" query result, we do not discard or delete the
> remaining items from the result list. As a result, the next time execute() is
> invoked, we will be retrieving the next item in line. Consequently, LAST_ONLY
> strategy will also execute all ready actions for a given coordinator job,
> making it no different than LIFO.
