---------------------------------------
[~risdenk] I'm back looking at this. I'm not sure where to add
{code:java}
permission javax.security.auth.kerberos.ServicePermission
"zookeeper/localh...@example.com", "initiate";
permission javax.security.auth.kerberos.ServicePermission
"zookeeper/localh...@example.com", "accept";
{code}
Understand I'm a total and complete Kerberos novice. I've @Ignored that test
for now so I can get through the rest of the tests. I had a million lines or so
of:

> Upgrade ZK dependency to 3.4.13. This fixes ZOOKEEPER-2184 which will make
> the ZK client re-resolve the server hostnames when a connection fails. This
> will fix issues where a failed ZK container is replaced with a new one that
> has a different IP address and DNS gets updated with the new address.
> Typically these upgrades do not require code changes, but that should be
> verified.
