Ankur,

You don't need to configure anything
in the Paho Java client, just provide a URI, client-id and (possibly) client WAL/persister.

This is what two MqttClient constructors do:

Also, you do not technically have to add a new user to RabbitMQ but if you connect
from remote hosts and want to use reasonable security practices, that's a good idea.

That said, in the latter case non-authenticated connections is not what you want.
