Subject [jira] [Commented] (YARN-249) Capacity Scheduler web page should show list of active users per queue like it used to (in 1.x)
Date Wed, 30 Jan 2013 21:39:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-249?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13566930#comment-13566930
] 

Thomas Graves commented on YARN-249:
------------------------------------



On the web ui I'd like to see us consistent with either using <> or [] for this and
the used resources.
It would be nice to somehow tell users what the % is next to memory and vcores but I can't
think of a good way to do that.

You should name the resourcesUsed the same between the queue and the user.  Also the parent
queues don't have the resourcesUsed object which I think they should. 

getUsers should make a new copy to return instead of returning the actual object to prevent
accidental modification of it. see getChildQueues in ParentQueue

In the resourcemanagerrest documentation it references perUserResources, which should just
be users, its also missing the active and pending apps.

> On the jobtracker, the web ui showed the active users for each queue and how much resources
each of those users were using. That currently isn't being displayed on the RM capacity scheduler
web ui.
