Hi All,
         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.

Please help.
