Once you have that, look inside your configuration directory ($CASSANDRA_HOME/conf for Tarball installs, /etc/cassandra for apt-get installs) and you will notice several files: cassandra.yaml, cassandra-env.sh, and cassandra-rackdc.properties among them.

In the cassandra.yaml file, make the following adjustments:

I'll name the cluster PermanentWaves:
