Hi Kant. it looks like ec2 instances cannot talk to each other using public IP's
"talk to each other" --> port 7000 (if not using ssl, 7001 if using it). Make sure this port is open. From IP_1: telnet ip_2 7000 will tell you if the port is opened. "using public IP's" --> Are you using Ec2Snitch or Ec2MultiRegionSnitch. The former uses exclusively private IP (listen_address, rpc_address and broadcast_address empty / commented). The latter uses public ip for broadcast_address. You need then to make sure ports are open between the private IPs. Having a look at 'nodetool status' before running operations should help you determine the current status for your cluster. Nodes should be showing UN status (Up, Normal).
