Subject [jira] [Commented] (YARN-8219) Add application launch time to ATSV2
Date Sun, 03 Feb 2019 06:19:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-8219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16759307#comment-16759307
] 

Abhishek Modi commented on YARN-8219:
-------------------------------------

[~vrushalic] launch time is only set once for the application and not for app attempt. This
won't be overridden for multiple app attempts. This is the time when first AM reached LAUCNHED
state for that particular application and thus I think, YARN_APPLICATION_LAUNCHED should be
used. In ApplicationReport also, it is associated with application rather than app attempt.

> YARN-7088 publishes application launch time to RMStore and also adds it to the YARN
UI. It would be a nice enhancement to have the launchTime event published into the ATSV2.
