James Cheng commented on KAFKA-3838:
------------------------------------

This JIRA moves ZKClient from 0.7 to 0.9. Can ZKClient 0.7 be used against Zookeeper 3.4.8? We are trying to figure out if we can upgrade our Zookeeper ensemble from 3.4.6 to 3.4.8, and still use Kafka 0.10.0.1. /cc [~fpj]

> Zookeeper 3.4.8 has some improvements, specifically it handles DNS Re-resolution when a connection to zookeeper fails. This potentially allows Round Robin DNS without the need to hardcode the IP Addresses in the config. 
> http://zookeeper.apache.org/doc/r3.4.8/releasenotes.html
> ZkClient has a new 0.9 release which uses zookeeper 3.4.8 which is already marked as stable.
> Tests are passing.
> Here is the PR: https://github.com/apache/kafka/pull/1504
