[jira] [Commented] (YARN-9438) launchTime not written to state
store for running applications
[ https://issues.apache.org/jira/browse/YARN-9438?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16899223#comment-16899223 ]
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 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).
