Subject [jira] [Commented] (YARN-2868) Add metric for initial container launch time to FairScheduler
Date Sat, 24 Jan 2015 00:55:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-2868?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14290291#comment-14290291
] 

Wangda Tan commented on YARN-2868:
----------------------------------

Just checked code, is it good to put in ClusterMetrics? aMRegisterDelay/amLaunchDelay seems
more related to such initial container allocation time.  And name of the metric could be "App
first container allocation delay".

Sounds good? [~rohithsharma].
