To change the cluster name:
1) Stop all nodes. 2) Delete or move the LocationInfo sstables from
/var/log/cassandra/data/system/LocationInfo3) Change the cluster_nam
Hey Aaron,
That worked beautifully. Thank you sir!

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. :)

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.

I think Arron meant /var/lib/cassandra (by default)
Check there (unless you changed you data directories in your cassandra.yaml)

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.

To change the cluster name:

You cannot do an incremental change of the cluster name. All nodes in the

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.

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

Hi Tim,
I had a similar problem and I sorted it out in the following manner.
The cluster name is stored in two places. In he cassandra.yaml and the
system keyspace. Everytime you start a node it checks the cluster name
in both these places. If changes in the configuration files is not

Hi Abhijit,
Thanks and actually I did restart cassandra at the end. I suspect I will
have to delete the files in my system keyspace folder. I'm not at liberty
to do that at the moment, but I will give that shot as soon as I'm able.
Thank you again

Hey Tim,
Can you repeat these steps as given below? I guess now you are missing
step no 6.
Start the Cassandra-cli connected to your node.
Run the following:
1. use system;
2. set LocationInfo[utf8('L')][utf8('ClusterName')]=utf8('Brisk
Cluster');
3. exit;
4. Run nodetool flush
whoops! sorry about that! trying again..
[default@unknown] connect beta.jokefire.com/9160;
Connected to: "Test Cluster" on beta.jokefire.com/9160
[default@unknown] use system;
Authenticated to keyspace: system
[default@system] set LocationInfo[utf8('L')][utf8('Cluster
Name')]=utf8('Jokefire Clust
If you have used the above commands then i guess problem lies in this step.
[default@system] set LocationInfo[utf8('L')][utf8('*Test
Cluster*')]=utf8('Jokefire
Cluster');
It should be like this: set LocationInfo[utf8('L')][utf8('Cluster
Name')]=utf8('Jokefire Cluster');
Hello,
Thanks for your replies.
DNS seems to be properly configured:
[root@beta:~] #host beta.jokefire.com
beta.jokefire.com has address 198.101.216.47
And I forgot the step to use the nodetool flush command. Taking it from the
top again:
[default@unknown] use system;
Authenticated to keyspac
have you flushed the node using NODETOOL after renaming the cluster?
Is your /etc/hosts correct? Does it have an entry for beta.jokefire.com
What if you replace beta.jokefire.com with the ip address, can you connect?
Can you telnet to beta.jokefire.com port 9160?
Look in the system log and see if you have a log entry like
INFO [main] CassandraDaemon.jav
Thanks! That got the value inserted properly
[default@system] set LocationInfo[utf8('L')][utf8('Test
Cluster')]=utf8('Jokefire Cluster');
Value inserted.
Elapsed time: 5 msec(s).
But if I go into the yaml file and set the cluster name
# The name of the cluster. This is mainly used to prevent m
[default@system] set LocationInfo[utf8('L')][utf8('Test
Cluster')]=utf8('Jokeire Cluster');
Value inserted.
You are missing set

hello,
I'd like to change my cluster name from the default 'Test Cluster' to
something a little more reflective of the site name. I am using cassandra
1.1.3.
So I tried following the instructions from the wiki, intending to modify
the cassandra.yaml file after I performed these steps:
