Subject [jira] [Commented] (HDFS-5956) A file size is multiplied by the replication factor in 'hdfs oiv -p FileDistribution' option
Date Tue, 25 Feb 2014 06:27:21 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5956?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13911297#comment-13911297

Haohui Mai commented on HDFS-5956:
----------------------------------

The patch looks good to me. One nit: can you please change the name of the unit test {{testFileDistributionVisitor}}
to {{testFileDistributionCalculator}}?

+1 once it is addressed.
