 Something that bit me on this (I've done it with both
 Cassandra and Hadoop boxes, and some problems
 might be more Hadoopy related) is hostname.

 You need to change /etc/hostname and probably (unless
 you're happy to reboot again) the commandline of this
 too, to change it in the current instance.

 I found it best to drop all Cass instances (drain then stop),
 just to be a bit more confident.
