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 14:53:59 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12768265#action_12768265

rahul k singh commented on MAPREDUCE-1105:

ran ant test for yahoo distribution, all testcases passed except 2.

    [junit] Test org.apache.hadoop.hdfs.server.namenode.TestStartup FAILED
    [junit] Test org.apache.hadoop.fs.loadGenerator.TestLoadGenerator FAILED

both are related to hdfs. Current patch has no relation with these  , it only modifies capacity

> 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.
