cassandra node discovery

votes

I just set up a 3 node system with ip addresses "192.168.0.101", "192.168.0.102", "192.168.0.103". I have set the seeds value on the configuration of all three machines as seeds: "192.168.0.101,192.168.0.102,192.168.0.103"

However, on running nodetool on any of them, only the 103 machine gets discovered.

node101:/opt/cassandra/apache-cassandra-0.8.5/bin# ./nodetool ring -h 192.168.0.101 Address DC Rack Status State Load Owns Token

Could someone tell me where the problem lies?

I would recommend

  1. Make sure you're on the latest stable release of Cassandra
  2. Start with a single node as seed on all machines (say, .101)

  3. Add this to log4j-server.properties:

    log4j.logger.org.apache.cassandra.gms=TRACE
