Subject [jira] Commented: (MAPREDUCE-1105) CapacityScheduler: It should be possible to set queue hard-limit beyond it's actual capacity
Date Wed, 21 Oct 2009 16:49:59 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12768326#action_12768326
] 

Hudson commented on MAPREDUCE-1105:
-----------------------------------

Integrated in Hadoop-Mapreduce-trunk-Commit #91 (See [http://hudson.zones.apache.org/hudson/job/Hadoop-Mapreduce-trunk-Commit/91/])
    . Remove max limit configuration in capacity scheduler in favor of max capacity percentage
thus allowing the limit to go over queue capacity. Contributed by Rahul Kumar Singh.

> Currently the CS caps a queue's capacity to it's actual capacity if a hard-limit is specified
to be greater than it's actual capacity. We should allow the queue to go upto the hard-limit
if specified.
> Also, I propose we change the hard-limit unit to be percentage rather than #slots.
