Subject [jira] [Commented] (YARN-685) Capacity Scheduler is not distributing the reducers tasks across the cluster
Date Fri, 12 Jul 2013 19:37:49 GMT

    [ https://issues.apache.org/jira/browse/YARN-685?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13707292#comment-13707292

Ravi Prakash commented on YARN-685:
-----------------------------------

I meant a randomwriter with 490 maps and 0 reduces. The sorter also had 490 maps, but 70 reduces.

> If we have reducers whose total memory required to complete is less than the total cluster
memory, it is not assigning the reducers to all the nodes uniformly(~uniformly). Also at that
time there are no other jobs or job tasks running in the cluster.
