I am trying the ring exercise on my mac. I am not using a VM. I have installed dse tarball provided in the DataStax Academy and configured 2 nodes and able to start up c* instances on them after setting up virtual n/w interface. But the 2 nodes are not forming a cluster. I made sure cluster_name and other configuration is same in cassandra.yaml file of both these nodes.
nmap reports that port 7000 is open on both 127.0.0.1 and 127.0.0.2 - ran nmap -p 7000 127.0.0.1 and nmap -p 7000 127.0.0.2
Can you please help understand why these 2 nodes are not joining to become one cluster?
