Can't connect from CQL to Cassandra 2.0.10

In the server config, I disabled lean ( start_rpc: false

) because presumably this is now deprecated. The server starts normally:

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

If I try to run CQL I get this error:

C:\Program Files\DataStax Community\apache-cassandra\bin> .\cqlsh.bat Connection error: Could not connect to localhost:9160

Port 9160 is a lean port. I was under the assumption that CQL had to work in its own format.

If I try to force the port:

C:\Program Files\DataStax Community\apache-cassandra\bin> .\cqlsh.bat localhost 9042

I get this:
