Port usage on Cassandra node

Not applicable

Hello!

What is impact on Cassandra node if tcp port 9042 is closed?

We have running cluster and I found that port is required per documentation but in reality it is not open in iptables.

Usually port 9402 is used for CQL native transport port. @Paul Mibus

This release of Edge uses Thrift for communication which happens on port 9160. Future releases may start using the native interface which will make use of 9402. Hope that helps.

@Prithpal Bhogill, I understand that it is CQL, but does it have impact on OPDK normal operation.
