Subject [jira] Updated: (MAPREDUCE-653) distcp can support bandwidth limiting
Date Tue, 08 Sep 2009 15:25:57 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-653?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ravi Gummadi updated MAPREDUCE-653:
-----------------------------------

    Attachment: d_bw.v1.patch

Attaching patch that has the suggested changes except the randomization of interval.
This patch applies after applying  MAPREDUCE-649, MAPREDUCE-654, MAPREDUCE-645, MAPREDUCE-664,
MAPREDUCE-661, MAPREDUCE-650, MAPREDUCE-648 and MAPREDUCE-564.

Because of making getNumRunningMaps() throw an Exception, testcase in earlier patch doesn't
work. So removed it in this patch. Couldn't think of an easy way of adding a testcase for
this.
