I made a few changes to the patch, almost all to make the patch adhere to the [code conventions|http://www.oracle.com/technetwork/java/javase/documentation/codeconvtoc-136057.html] ([wiki|https://wiki.apache.org/hadoop/HowToContribute]). Could you take a look and make sure this didn't accidentally break your changes? The only intended functional change was to {{Helper}} (renamed {{StatUtils}}), to use the {{recursive}} parameter.
