nosql - Cassandra port usage - how are the ports used?

Question

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?

Answer 1

@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
