[jira] [Commented] (YARN-451) Add more metrics to RM page

    [ https://issues.apache.org/jira/browse/YARN-451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14636358#comment-14636358 ] 

Joep Rottinghuis commented on YARN-451:
---------------------------------------

Just for the record, at Twitter we've been running with YARN-2417 in production and are finding it very useful in clusters of many thousands of nodes with tens of thousands of jobs in a day.

> ResourceManager webUI shows list of RUNNING applications, but it does not tell which applications are requesting more resource compared to others. With cluster running hundreds of applications at once it would be useful to have some kind of metric to show high-resource usage applications vs low-resource usage ones. At the minimum showing number of containers is good option.
