Subject [jira] [Commented] (YARN-656) In scheduler UI, "Memory Total" should not include reserved memory.
Date Wed, 08 May 2013 21:09:17 GMT

    [ https://issues.apache.org/jira/browse/YARN-656?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13652360#comment-13652360

Carlo Curino commented on YARN-656:

I haven't seen this problem happening with the CapacityScheduler (but I was not looking for
it, so I might just have missed it).
In the CapacityScheduler reservation count against your capacity, but you might be right that
they are not counted in the metrics.

> "Memory Total" is currently a sum of availableMB, allocatedMB, and reservedMB.  Including
reservedMB in this sum can make the total exceed the capacity of the cluster.
