Re: Failed to connect to a Cassandra cluster's all nodes without default port

Sorry I misunderstood your problem. I thought you have a cluster with different transport ports, which is not supported prior to Cassandra 4.

Turns out your cluster is using a uniform non-default transport port for every host. I am not 100% sure but seems this is fixed in Datastax java driver 4, which is included in JanusGraph 0.6.0. Can you try the master version of JanusGraph and see if you still have this problem?

Got it. It does not seem to be a JanusGraph problem. I didn’t dig deep into it but seems it’s a limitation of Cassandra. See https://datastax-oss.atlassian.net/browse/JAVA-1388#icft=JAVA-1388 and other tickets mentioned there.

Right now I would suggest you avoid using different native transport ports in the same Cassandra cluster.

Hi，
I am sorry to make you confused. I get the line number 220 from a .class file,  not a .java file.
the line number in java file is 246. you can read it from the screenshot
but I don't mean this line case the issue，just because  I this is a good position to set the port to replace the default port.
