Subject [jira] [Commented] (YARN-1756) capture the time when newApplication is called in RM
Date Sat, 01 Mar 2014 01:15:19 GMT

    [ https://issues.apache.org/jira/browse/YARN-1756?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13916677#comment-13916677

Zhijie Shen commented on YARN-1756:
-----------------------------------

What does "newApplication" meaning? Constructing the RMAppImpl instance? AFAIK, submitTime
is captured in ClientRMService, and before constructing the instance, there's just a few step
of sanity check. Therefore, the "newTime" will be quite close to submitTime.

> The application submission time ( when submitApplication is called) is collected by RM
and application history server. But it doesn't capture when the client calls newApplication
method. The delta between newApplication and submitApplication could be useful if the client
submits large jar files. This metric will be useful for https://issues.apache.org/jira/browse/YARN-1492.
