storage_port: Used for Gossip and Data exchange. So in your word, it is the port for the seeds.
You CAN change the storage_port, but all nodes in your ring need to use same storage_port number. That's why you need different IP address for each node. rpc_port: Used for Thrift which the Cassandra clients connect to. I can't understand why you can't change rpc_port. maki 2011/4/23 Tomas Vondra <t...@fuzzy.cz>: > Dne 23.4.2011 03:08, Jonathan Ellis napsal(a): >> You really need different IPs. > > OK, thanks.
