Subject [jira] [Commented] (YARN-3819) Collect network usage on the node
Date Mon, 29 Jun 2015 17:38:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-3819?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14605953#comment-14605953
] 

Lei Guo commented on YARN-3819:
-------------------------------

Moving the implementation into common, it may help to reduce the development effort and maintenance
of code, but still with extra overhead in a production environment because different component
need collect similar information. And as the polling could occur at different time for different
component, they may behave differently, 
Ideally, there should be one centrally place/component to collect node metrics and provide
related information to different services, something like the master LIM in Platform LSF.
Maybe the timeline service could take this role in the future.
