Hello All, My problem with Cassandra across region is solved. Thanks to Milind and Peter.
I was editing the Source, the two files MessagingService.java and OutboundTcpConnection.java correctly and even was able to build it successfully by referring the patch on http://www.mail-archive.com/user@cassandra.apache.org/msg05692.html. The problem was with the cassandra.yaml. In rpc_address filed, private ip should be used and in listen_address it should be public. I was trying with public ip in both the fields as well as by keeping both blank.

I believe "Cannot assign requested address" is the error you get with the official Cassandra because the external IP address is not the actual address of an adapter. The patches change the code so that it listens on all interfaces (so it should not actually be requesting a specific address) On Mon, Feb 28, 2011 at 06:23:53AM -0600, Himanshi Sharma wrote: > Hi Peter, > > I made changes as per ur patch.
