------------------------------------------
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}
