Hi Everyone,
I have an error starting a cassandra node. I have checked the 
configuration file cassandra.yaml where the cluster name is Brisk 
Cluster.Where as the when i start the node it give me exception with the 
cluster name as Test Cluster. I am using brisk-1.0-beta2 version.

ERROR 10:40:18,655 Fatal exception during initialization
org.apache.cassandra.config.ConfigurationException: Saved cluster name 
Test Cluster != configured name Brisk Cluster

org.apache.cassandra.db.SystemTable.checkHealth(SystemTable.java:255)
     at 
org.apache.cassandra.service.AbstractCassandraDaemon.setup(AbstractCassandraDaemon.java:128)
     at com.datastax.brisk.BriskDaemon.setup(BriskDaemon.java:73)

org.apache.cassandra.service.AbstractCassandraDaemon.activate(AbstractCassandraDaemon.java:315)

Could anyone help me solve the issue and let me know whats going on.

Thanks

Perform these steps on each node:
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 on this node.
   5. Update the cassandra.yaml file for the cluster_name
   6. Restart the node.

Don't forget to kept the the default cluster name Test Cluster  while
performing the initial operations

Regards,
Abhijit

Hi Ei,

Thanks a lot.IT worked. The node has started after deleting the files 
from the system keyspace.

Thanks

Hello Kumar,

If you've started cassandra on this node before, the cluster name would 
be stored in the system keyspace.
Everytime you start cassandra node, it will compare the value between 
the one in system keyspace and the one
in you configuration file, if they're not equal, you'll get an error.
To solve the problem, modify your config setting back or delete the 
files in your system keyspace folder except files like Schema*.*.

Please backup files before deletion in case something goes wrong.

Ei
