Subject [jira] [Commented] (MAPREDUCE-3326) RM web UI scheduler link not as useful as should be
Date Thu, 05 Jan 2012 19:24:40 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13180739#comment-13180739
] 

Jason Lowe commented on MAPREDUCE-3326:
---------------------------------------

Sorry I forgot to mention that the patch is implemented in terms of the web dao objects, so
the web services have access to the same information as the web page.  The web services tests
were updated as part of the patch to verify this.  I was going to update the web services
documentation, but Tom informed me that part hasn't been written yet.  Tom said he'd update
the docs to describe the new fields in the web dao objects before the first draft is submitted.
 If those docs go in before this patch then I can update the patch, or we can file a JIRA
to track updating the docs.

> The resource manager web ui page for scheduler doesn't have all the information about
the configuration like the jobtracker page used to have.  The things it seems to show you
are the current queues - each queues used, set, and max percent and then what apps are running
in that queue.  
> It doesn't list any of yarn.scheduler.capacity.maximum-applications, yarn.scheduler.capacity.maximum-am-resource-percent,
yarn.scheduler.capacity.<queue-path>.user-limit-factor, yarn.scheduler.capacity.<queue-path>.minimum-user-limit-percent,
queue state, active users and percent used by user
