Jonathan Hung commented on YARN-9438:
-------------------------------------
002 changes:
* Use the same ApplicationStateData constructor in RMAppImpl as in
RMStateStore#storeNewApplication
* Fix TestRMRestart#testRMRestartWaitForPreviousSucceededAttempt: first call
to updateApplicationStateInternal should not be skipped (first one is saving
launchTime), second one should be skipped
* Fix TestRMRestart#testClientRetryOnKillingApplication: similar to above.
TestMemoryRMStateStore's {{count}} is incremented when storing launchTime, so
increment the counts in this test accordingly
* Fix TestRMRestart#testRMRestartOnMissingAttempts: storing launchTime creates
a new ApplicationStateData in memory state store, hence move the app state
getter after the attempts have been launched
> launchTime not written to state store for running applications

> launchTime is only saved to state store after application finishes, so if
> restart happens, any running applications will have launchTime set as -1
> (since this is the default timestamp of the recovery event).
