Yes, change rpc_address to node B. Immutability aside, if Node A Cassandra and Node B Cassandra are using the same directory on the same shared filesystem, let's call it /cassandra/state/database, would that not be a problem? Or said differently, does not Node A need its own writable place /cassandra/state/database/nodeA and likewise /cassandra /state/database/nodeB for Node B's writable place?
Multinode Cassandra may not always be available due to resource constraints. Presumably multinode Cassandra for Node B is not free: it takes up network, cpu, and replicated disk space, no? Lou.
