Subject [jira] [Commented] (YARN-4751) In 2.7, Labeled queue usage not shown properly in capacity scheduler UI
Date Mon, 14 Mar 2016 18:25:33 GMT

    [ https://issues.apache.org/jira/browse/YARN-4751?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15193832#comment-15193832

Eric Payne commented on YARN-4751:
----------------------------------

Thanks, [~sunilg]. I will look into trunk's version of {{TestCapacitySchedulerNodeLabelUpdate}}.

Regarding the larger issue of how to fix this problem in 2.7, I am fine if you want to provide
a backport of some of the patches you mentioned. However, my biggest concern is the time and
effort that will take, along with the added risk. As I mentioned above, there seems to be
a lot of inter-dependencies that involve adding more features and fixes than just the one
documented by this JIRA. I'm not sure we want all of that complexity going back into 2.7.

> In 2.6 and 2.7, the capacity scheduler UI does not have the queue graphs separated by
partition. When applications are running on a labeled queue, no color is shown in the bar
graph, and several of the "Used" metrics are zero.
