/var/log/cassandra/data/system/LocationInfo3) Change the cluster_name
By the way, The cluster name is only cosmetic. It may not be worth to
change it since it induce a downtime and considering the mishandling risk.

Cool guys.. and thanks. I'll give this a shot. And I do understand it's a
cosmetic issue. It's just an OCD little detail I want to correct before my
cluster starts growing more nodes. :)

Hello,
I'm attempting to change my cluster name, yet retain my keyspace as it
was. I know from what I've read that this requires changing it within the
cassandra cli (using system), changing it in the cassandra.yaml file, and
deleting the contents of the /var/lib/cassandra/data/system directory.
To change the cluster name:
1) Stop all nodes.
2) Delete or move the LocationInfo sstables from
/var/log/cassandra/data/system/LocationInfo
3) Change the cluster_name in cassandra.yaml
4) Restart the nodes.
You cannot do an incremental change of the cluster name. All nodes in the
cluster
Hello,
And thanks for your reply! Well so far it's just a single node. So I
wouldn't think this should be so complicated. But one day hopefully from
this node a cluster will grow, but that we shall have to wait and see.
At any rate, at /var/log/cassandra I don't see a directory called system.

Check there (unless you changed you data directories in your cassandra.yaml)
