TFramedTransport needs to be used with Cassandra 0.7.  Buffered transport was the default for 0.6, but it was changed to framed for 0.7.

I'm using Cassandra 0.7beta3 and it's running on localhost:9160 and Python works with it just fine. So, I go to run C++ against the system and I get:

TTransportException: No more data to read.

I did the thrift --gen cpp interface/cassandra.thrift in my 0.7beta3 folder
then included those files in the C++ code, and it builds fine, and runs.

It bombs out on the set_keyspace call... the code is short so I'll paste it here (not counting includes and using calls):


const string host("localhost");
const int port= 9160;

int main()
    try {
        boost::shared_ptr<TSocket> socket(new TSocket(host, port));
        boost::shared_ptr<TTransport> transport(new TBufferedTransport(socket));
        boost::shared_ptr<TProtocol> protocol(new TBinaryProtocol(transport));

        CassandraClient client(protocol);

        string version;
    } catch (apache::thrift::transport::TTransportException &tte) {
        cout << "TTransportException: " << tte.what() << endl;
    return 0;


It throws this same error with a series of other calls. This is probably (hopefully) something stupid I'm missing. Do I really need to run the C++ server component (which seems superfluous since it's not actually my Cassandra instance) as detailed here:
