How to adjust configuration to own environment?

Hi all
I am using and would I like to override default configuration.
The default configuration can be found on

For example, I would like to override the following options

contact-points = [""]
# To connect to the Cassandra hosts with credentials.
# Authentication is disabled if username is not configured.
authentication.username = ""
authentication.password = ""

The question is, how to do it?
