This thread could have been much shorter with a judicious use of "grep", heh ...

<user@hostname># grep -i name /etc/cassandra/cassandra.yaml
cluster_name: 'QA Cass Cluster'

<user@hostname> # grep 'Cass Cluster' /mnt/cassandra/data/system/*
Binary file /mnt/cassandra/data/system/LocationInfo-hd-5-Data.db matches

Just remove "LocationInfo" files from the system keyspace when
changing Cluster Names. Nuking the other stuff is not necessary.
