This error relates to the Cassandra daemon not starting up.

Incorrect entries in the cassandra configuration file: cassandra.yml

Clean up old dataset.

$ sudo rm -rf /var/lib/cassandra/data/system/*

Ensure entries in cassandra.yml are configured correctly.

$ sudo vi /etc/cassandra/conf/cassandra.yaml

Pay particular attention to the seed addresses and listen_address, if the installation is on a localhost, single node, keep seed as localhost and the listen_address as localhost.
