Subject [jira] [Commented] (YARN-4392) ApplicationCreatedEvent event time resets after RM restart/failover

Naganarasimha G R commented on YARN-4392:
-----------------------------------------

Hi [~xgong],
wrt YARN-4392.2.patch, is it required to send the App created event to ATS, during restore?
, as even before we store the app information in the RM state store we would have pushed this
app created event to ATS.
