The Cassandra Contact Points property expects a hostname or IP followed by a colon and then the port number where the Cassandra node is listening. So if you have 3 nodes at:

node-0.servername.com:9042
node-2.servername.com:9042
node-3.servername.com:9042

Your Contact Points setting would be:

node-0.servername.com:9042,node-2.servername.com:9042,node-3.servername.com:9042
