Github user hanm commented on the issue:
https://github.com/apache/zookeeper/pull/580
And yes like others commented, please rebase and resolve conflicts, and
reply to previous unattended comments. My previous comments need address are:
* Existing unit test failures and one findbug issue.
* Are there more types of metrics going to be added, such as Gauge?
* Would be good to have some tests around the system.---
