@asdf2014 : There are lots of formatting changes in this patch, which makes
review harder. Can you please update the patch to avoid those formatting
changes? See [How To
Contribute](https://cwiki.apache.org/confluence/display/ZOOKEEPER/HowToContribute):
## Please don't do in pull request:
reformat code unrelated to the bug being fixed: formatting changes should
be separate patches/commits.
