Subject [jira] [Commented] (YARN-2664) Improve RM webapp to expose info about reservations.
Date Wed, 03 Dec 2014 23:55:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-2664?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14233690#comment-14233690

Carlo Curino commented on YARN-2664:
------------------------------------

I am running this on a 35 machine cluster, with a (modified) gridmix generating reservations
and submitting jobs. 
It looks really nice (I am attaching a screenshot), well done [~mazzu]. 

One simple nice addition would be to show, beside the absolute memory assigned to the reservations,
something that gives an idea of the overall plan utilization.  For example, you can add next
to the absolute values on the Y axis, some reference to the plan percentage (even just for
the highest value).

> YARN-1051 provides a new functionality in the RM to ask for reservation on resources.
Exposing this through the webapp GUI is important.
