             Summary: Feed status fails with NPE post update when the new coordinator is in PREP state
                 Key: FALCON-378
                 URL: https://issues.apache.org/jira/browse/FALCON-378
             Project: Falcon
          Issue Type: Bug
          Components: oozie
    Affects Versions: 0.4
            Reporter: Venkatesh Seetharam


An NPE is thrown for status calls post feed update briefly between the new coord creation transitioning from PREP to RUNNING at:

{code}
org.apache.falcon.workflow.engine.OozieWorkflowEngine#getCoordActions
                Date iterEnd = (coord.getNextMaterializedTime().before(end) ? coord.getNextMaterializedTime() : end);
{code}

coord.getNextMaterializedTime() is null since the coord is in PREP state as the new coord's effective time is set as now() + 3 min. In reality, this is greater than 3 mins is my observation.

{code}
Feed updated at:
Current time = Tue, 25 Mar 2014 21:54:00 GMT

Old Coord: 
Start time = Tue, 25 Mar 2014 00:00:00 GMT
End time = Tue, 25 Mar 2014 22:00:00 GMT
Status = RUNNING

New Coord:
Start time =  Tue, 25 Mar 2014 22:00:00 GMT
End time = Wed, 26 Mar 2014 00:00:00 GMT
Status = PREP
{code}
