Subject [jira] Commented: (HADOOP-4178) The capacity scheduler's defaults for queues should be configurable.
Date Fri, 26 Sep 2008 09:03:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4178?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12634789#action_12634789

Hemanth Yamijala commented on HADOOP-4178:
------------------------------------------

Looks mostly right. Couple of points:

- I think it will be best to fail if the configured values are invalid. Hiding it may show
up as problems later.
- The computation for percentages are a float value, so I don't see the need to round still.
There is some rounding done anyway when the actual capacity is computed. Let's handle any
rounding related issues at one place there. I think the computation of the allocated capacity
should be simple, and just divided equally at the configuration level.
