Subject Cassandra With C++
Date Mon, 08 Nov 2010 18:55:28 GMT
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);
        transport->open();

        string version;
        client.set_keyspace("Crawldata");
        transport->close();
    } 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:
