Another option to consider is to add the port 7199 to the firewall or just to test it to see if you can access a 2 node system is to turn off the firewall in linux using " sudo service firewalld stop"

[dse@orion conf]$ dsetool status mars

DC: Cassandra Workload: Cassandra Graph: no

This has "nothing" to do with cassandra.

The documentation (regarding NoRouteToHostException) states that:

"Signals that an error occurred while attempting to connect a socket to a remote address and port. Typically, the remote host cannot be reached because of an intervening firewall, or if an intermediate router is down. "
