Subject [jira] [Commented] (YARN-1756) capture the time when newApplication is called in RM
Date Sat, 01 Mar 2014 01:25:19 GMT

    [ https://issues.apache.org/jira/browse/YARN-1756?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13916686#comment-13916686
] 

Ming Ma commented on YARN-1756:
-------------------------------

In between newApplication and submitApplication, MR client needs to copy local jars to HDFS
as part of job submission. For applications that submit large jars, this could take couple
seconds or more. https://issues.apache.org/jira/browse/YARN-1492 will reduce the delta.

> 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.
