You can leave them blank unless you're using mirror maker, in that case, you have to fill up those values using:
Comma-separated list of IP:port (or hostname:port) pairs of brokers on destination cluster. This should be more than one, for high availability, but there's no need to list all brokers.
Comma-separated list of IP:port (or hostname:port) pairs of brokers on source cluster. This should be more than one, for high availability, but there's no need to list all brokers.
