Impact on running cassandra cluster from changing hostnames...
Folks-
What is the correct process of changing the hostnames and IPs of each
server in a cassandra cluster. In my use-case we're shutting it down and
then changing the names and ips. No changes to hardware during the
processes. Beyond config changes, what should I be concerned about?

It's supposed to work, but it's definitely a rare thing to do.
You should be concerned about other nodes rejecting the new node
saying "remember this token? i'm at ip Y now instead of Z." if that
happens then shutting down all nodes and restarting will fix it.
