Steve Loughran commented on HADOOP-18384:
-----------------------------------------
Go ahead, but know i've locked down the branch until i can get it into trunk.
i want to get my last changes (with class renames and moves) in, then apply the
whole branch to trunk as one single patch...after which all changes can be
there. no more rebasing, merge pain shared by all....

> maybe its just the fs stats aren't being reset between test cases
