やってみたら
cassandra-cli -h myhost.compute-1.amazonaws.com
問題なく接続できます。astyanaxを使用することで、それも機能します。
ただし、playOrmで、ホスト文字列をに設定するmyhost.compute-1.amazonaws.com:9160と、ホストリストでコンマ区切りの文字列を使用する必要があると文句を言います。myhost.compute-1.amazonaws.com:9160,またはを使用するmyhost.compute-1.amazonaws.com:9160,myhost.compute-1.amazonaws.com:9160と、次の例外が発生します。
リモートホストに接続するための接続文字列をどのように設定する必要がありますか？
