Subject [jira] [Commented] (YARN-451) Add more metrics to RM page
Date Fri, 13 Sep 2013 18:23:53 GMT

    [ https://issues.apache.org/jira/browse/YARN-451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13766759#comment-13766759
] 

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

I am pretty close to getting a patch ready for review on this. A quick question before that
however: the proposed change contains changes in YARN (changes in message definition to carry
this extra info, and subsequent UI changes) and mapreduce (mapreduce application providing
this information).

Should I create two sub-tasks (one for YARN and one for MAPREDUCE) and provide separate patches
for them?

> 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.
