> currently when a kafka client fails to connect to a cluster, users see something like this:
> {code}
> Connection to node -1 terminated during authentication. This may indicate that authentication failed due to invalid credentials. 
> {code}
> that log line is mostly useless in identifying which (of potentially many) kafka client is having issues and what kafka cluster is it having issues with.
> would be nice to record the remote host/port
