Yeah that certainly seems to be the way forward, thanks.
Made adjustments but I'm still coming up short, the set strategy class
method has no javadoc and I'm getting a
InvalidRequestException(why:org.apache.cassandra.locator.RackUnawareStrategy
)
Am I doing this right, in the old config xml file you specified the full
path to the class, has that changed too?
public static void main(String[] args) throws InvalidRequestException,
TException {
TFramedTransport transport = new TFramedTransport(new
TSocket("localhost", 9160));
Cassandra.Client client = new Cassandra.Client(new
TBinaryProtocol(transport));
transport.open();
KsDef ks = new KsDef();
CfDef cf = new CfDef();
cf.setColumn_type("Standard");
cf.setName("Standard1");
cf.setKeyspace("Keyspace1");
List<CfDef> cl = new ArrayList<CfDef>();
cl.add(cf);
ks.setReplication_factor(1);
ks.setStrategy_class("org.apache.cassandra.locator.RackUnawareStrategy");
ks.setName("Keyspace1");
ks.setCf_defs(cl);
client.system_add_keyspace(ks);
}

Try this :
TFramedTranspor transport = new TFramedTransport(new TSocket(host, port));
Cassandra.Client cassandraConn = new Cassandra.Client(new
TBinaryProtocol(transport));
transport.open();
It is now Framed transport ;-)
Hope that helps

Hi everyone.
I'm having a bit of a problem getting started with 0.7
I had 0.6.4 working and I want to start checking out 0.7, I can't figure out
how to create keyspaces to even get started.
Can anyone also give me a little info on secondary index's, their purpose
and use
The following is the java code I was using
public class Client {
private static TTransport tr = null;
private static Cassandra.Client client = null;
public static Client Cassandra = new Client();
public Client() {
setupConnection();
}
private static void setupConnection() {
try {
tr = new TSocket("localhost", 9160);
TProtocol proto = new TBinaryProtocol(tr);
client = new Cassandra.Client(proto);
tr.open();
} catch (TException ex) {
Logger.getLogger(Client.class.getName()).log(Level.ALL,
null, ex);
}
}
public static void main(String[] args) throws InvalidRequestException,
TException {
KsDef ks = new KsDef();
CfDef cf = new CfDef();
cf.setColumn_type("Standard");
cf.setName("Standard1");
cf.setKeyspace("Keyspace1");
List<CfDef> cl = new ArrayList<CfDef>();
cl.add(cf);
ks.setReplication_factor(1);
ks.setStrategy_class("org.apache.cassandra.locator.RackUnawareStrategy");
ks.setName("Keyspace1");
ks.setCf_defs(cl);
Client.Cassandra.client.system_add_keyspace(ks);
}
}
But of course it throws an exception:

I've seen http://wiki.apache.org/cassandra/LiveSchemaUpdates and
http://wiki.apache.org/cassandra/API (CFdef and KSDef section)
But I still can't suss it any help/pointers would be much appreciated.
P.S I also used Hector with 0.6.4 so examples using either thrift or Hector
should get me going.
thanks
