Cassandra port usage – how are the ports used?

@Schildmeijer is largely right, however port 7001 is still used when using TLS Encrypted Internode communication

So my complete list would be for current versions of Cassandra:

  • 7199 – JMX (was 8080 pre Cassandra 0.8.xx)
  • 7000 – Internode communication (not used if TLS enabled)
  • 7001 – TLS Internode communication (used if TLS enabled)
  • 9160 – Thrift client API
  • 9042 – CQL native transport port
