@magsol - search for makeQualified() in the legacy and anything that has an
extra path in the args needs to be reverted back to original shape and form.
Why was this change done? Was originally intended to be upgraded all
deprecated MR apis to Hadoop 2, but the attempt went all Whack!! . So much for
trying to push code at 4:30AM.
