> ACCUMULO-3216 revealed a problem with users mixing and matching host identification schemes.
Users should be careful to identify hosts consistently. 
> We should make this recommendation in the user manual indicating a preference for DNS/hostnames
over IP addresses (because it's easier to make configuration changes and is required for Kerberos-enabled
Hadoop, and in general is more robust).
> We could also add a one-time warning during {{accumulo init}} or when services are started
if we see an IP address in the configuration rather than a hostname, just to make sure users
are aware of potential pitfalls.
