Subject Re: Impact on running cassandra cluster from changing hostnames...
Date Fri, 03 Sep 2010 15:10:50 GMT
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.
