Subject [jira] Commented: (MAPREDUCE-653) distcp can support bandwidth limiting
Date Fri, 05 Mar 2010 09:36:28 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-653?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12841778#action_12841778

Ravi Gummadi commented on MAPREDUCE-653:

We need to experiment and check if this way of asking JobTracker for counters from each map
task will be a considerable overhead on JobTracker(and would this make JobTracker heavily
loaded serving these many requests, with lot more new connections to JobTracker).
