Subject [jira] [Commented] (YARN-451) Add more metrics to RM page
Date Mon, 12 Aug 2013 23:25:48 GMT

    [ https://issues.apache.org/jira/browse/YARN-451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13737518#comment-13737518

Sangjin Lee commented on YARN-451:
----------------------------------

For sorting, it would be good to expose a number. How about the number of containers (used
+ reserved = needed)? I think the resource info (memory, vCores, etc.) may be bit redundant
at least UI-wise if the number of containers is displayed.

> 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.
