--------------------------------------
Hi [~sbarrier], I looked at this and agree that it's a typo and that your
proposed fix works. Could you make a diff from the project root (name it
something like "hadoop-10531-1.patch") and attach it to this JIRA? I'll then +1
and commit it.
A lot of work I know for a 1-character patch, but that's our process :)
