Cassandra version 2.1.8

Is it mandatory for all nodes of cassandra cluster to have same cluster name ?

Solution

  • Answer is YES. Otherwise, you'll get the following error.

    Example ERROR for different cluster_name:

    ERROR [main] 2014-02-25 01:51:17,377 CassandraDaemon.java (line 237) Fatal exception during initialization
org.apache.cassandra.exceptions.ConfigurationException: Saved cluster name Test Cluster != configured name thisisstupid

    at org.apache.cassandra.service.CassandraDaemon.activate(CassandraDaemon.java:462)
    at org.apache.cassandra.service.CassandraDaemon.main(CassandraDaemon.java:552)

    It is mandatory to have the same cluster_name for every single node in a cluster.
