Ying Zheng commented on FALCON-1602:
------------------------------------

Thanks for bringing this up, [~pallavi.rao]. This is also useful for instance search with
Titan DB based on ActiveMQ notifications. Do you plan to include consistency check with Oozie
for all job status including running and waiting?

When activemq is down for sometime, and oozie fails to send notifications of completion of
workflows of process instances even after retries. Then those instances won't mark as completed
in Falcon state store. Then for that processes new instances won't be launched assuming old
one's still running. There should be some recoverability in these cases.
