When experimenting with Cassandra I've observed that Cassandra listens to the following ports:

  • TCP *:8080
  • TCP *:8888
  • TCP *:57311
  • TCP *:57312
  • TCP 127.0.0.1:7000
  • TCP 127.0.0.1:9160
  • UDP 127.0.0.1:700

How does Cassandra use each of the ports listed?

@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
