Adding Nodes to a Cluster | DataStax Cassandra 0.7 Documentation

leave a comment »

Do not think of a seed node as a “master,” or “central” node. Seeds are contacted by new nodes joining the ring using the address you provide in the seeds list. At that time, seeds provide the new nodes information about the ring – what other nodes are included in it, what are their locations, and so on. After a node joins the ring, it shares ring information through the gossip protocol, and does not make any further special contact with the seed node.There is no strict rule to determine which hosts need to be listed as seeds, but all nodes in a cluster should have the same seed list. For a production deployment, DataStax recommends two seeds per data center.
