When I configured rpc_address with public IP, cassandra is not starting up. It's trowing 'unable to create thrift socket on <public IP>. When I changed it to private IP, it was good.
java.lang.RuntimeException: Unable to create thrift socket to /220.127.116.11:9160
Caused by: org.apache.thrift.transport.TTransportException: Could not create ServerSocket on address /18.104.22.168:9160.
Internally the public DNS resolves to the private IP.Though I configured the listen_address with public dns, still I had the same issue.describe_ring() returns includes the registered RPC addresses for the nodes. Trying setting the rpc_address to the public IP.looks like describe_ring() is the one which provides the details.CheersOn 11/12/2012, at 11:32 PM, santi kumar <firstname.lastname@example.org> wrote:We have a 4 node cluster in us-east region in two different AZ's.

Hector clients are initialized with public DNS names, then listern_address is with private ip and rpc_address is with 0.0.0.0.
Having issues with Node Auto Discovery by Hector. When it's trying to discover the ring, the end points are initialized with private IP's for all Token Ranges. It checks with the existing hosts (which are initialized public DNS) and thinks that there is a new node got added to the cluster.

Any idea, what is the best way to configure for EC2. Have gone through the link
But not sure whether it's fixed in 1.1.4. When I run the nodetool ring, it gives the private ips. But in the above doc, it shows the public IPs as part of nodetool ring.
Some insight into this is really helpful.
