    [ https://issues.apache.org/jira/browse/HADOOP-2978?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12577079#action_12577079

Owen O'Malley commented on HADOOP-2978:

+1 on this, although a unit test would be good.

Should we make a 0.16.2 target for this?
