ZooKeeper client > 3.4.6

[Bill de hÓra]

Hi,

I was wondering if anyone has experience (good or bad!) running Kafka 
with a ZooKeeper client > 3.4.6.

The reason to do this is to avoid having to bounce brokers when 
ZooKeeper node IPs change; it seems the 3.4.6 client caches IP addresses 
indefinitely but this may have be fixed in later versions.

(I noticed that in 
https://github.com/apache/kafka/commit/4c6d7ed95a05e1f08e820305afbab983822e8b82, 
ZooKeeper was bumped to 3.4.8, but the latest 0.10.0.1 still embeds 3.4.6.)
