Are you using different regions in ec2
Hi Anurag,We're using an elastic IP for the seed address (public DNS name should also work) and using the private IP (10.255.x.x) for the listen address.As you're getting started, you may also find this blog that my team put together helpful:

I am trying to install cassandra on ec2 boxes . I am using domain names to specify the listen_address and seeds.
I am getting following error from cassandra when I try to create keyspace.
Warning: unreachable nodes IP(address of the cassandra instance).. schemas agree across the cluste... schemas agree across the cluster
but when I do telnet IP address 9160 and telnet IPaddress 7000 it works fine.
