Since 0.7 beta 2 or something, locators have differents names.
In conf/cassandra.yaml :
Out of the box, Cassandra provides
# * org.apache.cassandra.locator.SimpleStrategy
# * org.apache.cassandra.locator.NetworkTopologyStrategy
# * org.apache.cassandra.locator.OldNetworkTopologyStrategy
Good luck

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:
Exception in thread "main"
_org.apache.thrift.transport.TTransportException_

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
