---------------------------------------
LGTM, +1.
I have some concerns if it will detect false negatives but can't think of any.

> - Could not login: the client is being asked for a password, but the
> Zookeeper client code does not currently support obtaining a password from
> the user. Make sure that the client is configured to use a ticket cache
> (using the JAAS configuration setting 'useTicketCache=true)' and restart the
> client. If you still get this message after that, the TGT in the ticket cache
> has expired and must be manually refreshed. To do so, first determine if you
> are using a password or a keytab. If the former, run kinit in a Unix shell in
> the environment of the user who is running this Zookeeper client using the
> command 'kinit <princ>' (where <princ> is the name of the client's Kerberos
> principal). If the latter, do 'kinit -k -t <keytab> <princ>' (where <princ>
> is the name of the Kerberos principal, and <keytab> is the location of the
> keytab file). After manually refreshing your cache, restart this client. If
> you continue to see this message after manually refreshing your cache, ensure
> that your KDC host's clock is in sync with this host's clock.
