Bowen Zhang commented on OOZIE-1319:
------------------------------------

correction for my second point. In the second scenario, actions from 9:00 am to 
9:50 am will be correctly skipped, but actions from 10:00 am till 10:50 am will 
run to "SUCCEDDED".

> "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.
