Subject [jira] [Commented] (YARN-2984) Metrics for container's actual memory usage
Date Tue, 20 Dec 2016 09:36:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-2984?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15763763#comment-15763763

Chuan Jin commented on YARN-2984:
---------------------------------

I upgrade my cluster to this version from 2.5.2 , but soon realize that my ganglia servers
have run out of disk space. The container metrics data is huge especially in large clusters,
 and less valuable than the service metrics  in most time. So why not change the default value
of  yarn.nodemanager.container-metrics.enable to false,  that may be more reasonable in a
production environment.

> It would be nice to capture resource usage per container, for a variety of reasons. This
JIRA is to track memory usage. 
> YARN-2965 tracks the resource usage on the node, and the two implementations should reuse
code as much as possible.
