Question

I have an exception occurred, using cassandra with thrift. I want to insert some data. Here is the java code:

package pacan.java.eee;
import java.nio.ByteBuffer;
import org.apache.cassandra.thrift.Cassandra;
import org.apache.cassandra.thrift.Column;
import org.apache.cassandra.thrift.ColumnParent;
import org.apache.cassandra.thrift.ConsistencyLevel;
import org.apache.cassandra.thrift.InvalidRequestException;
import org.apache.cassandra.thrift.NotFoundException;
import org.apache.cassandra.thrift.TBinaryProtocol;
import org.apache.cassandra.thrift.TimedOutException;
import org.apache.cassandra.thrift.UnavailableException;
import org.apache.thrift.TException;
import org.apache.thrift.protocol.TProtocol;
import org.apache.thrift.transport.TFramedTransport;
import org.apache.thrift.transport.TSocket;
import org.apache.thrift.transport.TTransport;

public class Main {

    private static final String UTF8 = "UTF8";

    /**
     * @param args
     * @throws TException 
     * @throws InvalidRequestException 
     * @throws NotFoundException 
     * @throws TimedOutException 
     * @throws UnavailableException 
     */
    public static void main(String[] args) throws InvalidRequestException, TException, NotFoundException, UnavailableException, TimedOutException {
        TTransport tr = new TFramedTransport(new TSocket("localhost", 7199));
        TProtocol protocol = new TBinaryProtocol(tr);
        Cassandra.Client client = new Cassandra.Client(protocol);
        tr.open();
        client.set_keyspace("keyspace");
        ColumnParent colParent = new ColumnParent("User");
        ByteBuffer rowid = ByteBuffer.wrap("100".getBytes());
        Column column = new Column();
        column.setName("description".getBytes());
        column.setValue("some value".getBytes());
        column.setTimestamp(System.currentTimeMillis());
        client.insert(rowid, colParent, column, ConsistencyLevel.ONE);
        tr.flush();
        tr.close();
    }

}

And here is the exception I got:

Help, please! =) I’ve already google it, and wasn’t able to find an answer.

Answer 1

• Have you defined/created a keyspace with name “keyspace”?
• Are you sure that you’re running thrift/rpc on port 7199 (default is 9160).
