Hi,
I am trying t= o rename a cluster by following the instruction on Wiki:

=

Cassandra says "ClusterName mismatch: = oldClusterName !=3D newClusterName" and refuses to start

=0A
To prevent =0Aope= rator errors, Cassandra stores the name of the cluster in its system =0Atab= le. If you need to rename a cluster for some reason, you can: <= /span>
Perform these steps on each node:
  1. Start the cassandra-cli connected = locally to this node.
    <= /li>
  2. Run the following:
  3. use system; =
  4. set LocationInfo[utf8('L')][utf8('= ClusterName')]=3Dutf8('<new cluster name>');
  5. exit;
  • Run nodetool flush on t= his node.
  • Upda= te the cassandra.yaml file for the cluster_name as the same as 2b).
  • Restart the node.
    • Once all nodes have been had this = operation performed and restarted, nodetool rin= g should show all nodes as UP.

    Get the following error:
    =
    Connected to: "Test C= luster" on 10.200.128.151/9160
    Welcome to Cassandra CLI version 1.1.6

    system keyspace is not user-modifiable.
