If I try
cassandra-cli -h myhost.compute-1.amazonaws.com
I connect to it with no problems. By using astyanax, it also works.
However, in playOrm, if I set my host string to myhost.compute-1.amazonaws.com:9160, it complains I need to use a comma separated string with the host list. If I use myhost.compute-1.amazonaws.com:9160, or myhost.compute-1.amazonaws.com:9160,myhost.compute-1.amazonaws.com:9160, I get the following exception.
How should I set the connection string to connect to a remote host?

The code is expecting a real cluster to run 2 or more nodes not a single node. (sorry, was on thanksgiving vacation). Do you need to connect to just a single node?
Also, the reason we have detection in there is so we do CL_ONE if you only have one node but we assumed probably incorrectly people would only use one node to play around with cassandra(ie. localhost). We didn’t think they would actually go live with just one node. Do you need modifications? If so, let us know and we can change that.
thanks,
Dean
