Question

I know there are several threads about the NoHostAvailableException but they simply don\'t provide a solution to my problem.

I can\'t connect to Cassand

Answer 1

Check your casssandra.yaml file. The native_transport uses the same address binding as the rpc_address. If it is bound to another address than "54.221.241.107" you would get this problem. Try setting it to

rpc_address: 0.0.0.0 

or to

rpc_address: 54.221.241.107  

and see if it helps. Keep in mind that ec2-ips might change on restarts.

My guess is that is is bound to the internal ip of the ec-2. And remember to add some security if you are opening up your database to the public this way :-)
