Subject [jira] [Commented] (YARN-3293) Track and display capacity scheduler health metrics in web UI
Date Wed, 08 Apr 2015 17:12:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-3293?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14485557#comment-14485557

Craig Welch commented on YARN-3293:
-----------------------------------

Your call, I think it's also fine to wait to do this until we do FairScheduler integration
when we are clear on exactly what needs to happen (it may be premature to do it now, not entirely
sure), but ultimately I think as much as can be shared should be.

> It would be good to display metrics that let users know about the health of the capacity
scheduler in the web UI. Today it is hard to get an idea if the capacity scheduler is functioning
correctly. Metrics such as the time for the last allocation, etc.
