We are currently using Zookeeper server 3.4.8, which includes the ZOOKEEPER-1506 fix.  However, the bug I am describing cannot be fixed on the server side as it happens when the server (and the host it runs on) are down.  The client fails to deal properly with the UnknownHostException and does not fall back to using the other Zookeeper servers in the cluster.

> We should upgrade zookeeper to 3.4.9 as it brings in a lot of stability improvements (http://zookeeper.apache.org/releases.html) and storm is still using 3.4.6 (https://github.com/apache/storm/blob/master/pom.xml)
> One serious issue affecting zookeeper 3.4.6 is https://issues.apache.org/jira/browse/ZOOKEEPER-1506 which prohibits zookeeper from getting a quorum and hence affects storm's stability as well.
