Subject [jira] [Commented] (YARN-2965) Enhance Node Managers to monitor and report the resource usage on the machines
Date Tue, 16 Dec 2014 00:13:14 GMT

    [ https://issues.apache.org/jira/browse/YARN-2965?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14247474#comment-14247474
] 

Karthik Kambatla commented on YARN-2965:
----------------------------------------

I am assuming there will be a config to turn on/off resource-tracking; for now, we need not
expose this config to the end-user. In addition to this config, I think it might make sense
to add a config to turn reporting to the RM on/off; people might just want to log this information
through metrics. 

Slightly orthogonal - we were thinking of tracking the resource usage per container as well.
Do you think this work can be extended to collect but not report that information as well?

> This JIRA is about augmenting Node Managers to monitor the resource usage on the machine,
aggregates these reports and exposes them to the RM.
