在服务器配置中，我已禁用thrift（start_rpc: false），因为可能是现在遗留的。服务器启动正常：
INFO 12:23:09,658 Starting listening for CQL clients on localhost/127.0.0.1:9042...
INFO 12:23:09,668 Not starting RPC server as requested. Use JMX (StorageService->startRPCServer()) or nodetool (enablethrift) to start it
如果我然后尝试启动CQL，我会收到此错误：
C:\Program Files\DataStax Community\apache-cassandra\bin> .\cqlsh.bat
Connection error: Could not connect to localhost:9160
港口9160是节俭港口。我假设CQL应该以原生格式运行。
如果我试图逼迫端口：
C:\Program Files\DataStax Community\apache-cassandra\bin> .\cqlsh.bat localhost 9042
我明白了：

答案 0 :(得分：2)
Cassandra 2.0.x的cqlsh使用Thrift与服务器通信。
