Subject [jira] [Commented] (YARN-4285) Display resource usage as percentage of queue and cluster in the RM UI
Date Mon, 21 Mar 2016 22:10:26 GMT

    [ https://issues.apache.org/jira/browse/YARN-4285?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15205262#comment-15205262
] 

Jian He commented on YARN-4285:
-------------------------------

[~vvasudev], [~leftnoteasy], looks like the % of queue/cluster for the app does not include
reserved resources. However, the queue's used resource in the UI does include reserved resource
too. This caused the total amount of resources for all apps in the table does not equal to
the total used resource shown in the queue.
Should we consider reserved resource too in the % of queue/cluster for an app ?

> Currently, we display the memory and vcores allocated to an app in the RM UI. It would
be useful to display the resources consumed as a %of the queue and the cluster to identify
apps that are using a lot of resources.
