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 keyspace: system [default@system] set LocationInfo[utf8('L')][utf8('Test Cluster')]=utf8('Jokefire Cluster'); Value inserted. Elapsed time: 31 msec(s). [default@system] exit; Then I ran nodetool flush: [root@beta:/etc/alternatives/cassandrahome] #./bin/nodetool -host beta.jokefire.com flush Then I update the cluster name in the yaml file: # The name of the cluster. This is mainly used to prevent machines in # one logical cluster from joining another. cluster_name: 'Jokefire Cluster' And if I try to start cassandra I see the following error: ERROR 11:32:45,278 Fatal exception during initialization org.apache.cassandra.config.ConfigurationException: Saved cluster name Test Cluster != configured name Jokefire Cluster at org.apache.cassandra.db.SystemTable.checkHealth(SystemTable.java:299) at org.apache.cassandra.service.AbstractCassandraDaemon.setup(AbstractCassandraDaemon.java:169) at org.apache.cassandra.service.AbstractCassandraDaemon.activate(AbstractCassandraDaemon.java:356) at org.apache.cassandra.thrift.CassandraDaemon.main(CassandraDaemon.java:107) Not sure what else I might be doing wrong here, but it would be great to hear what someone else thinks of this. Thanks!
