I Need some help

[Walter Dal Mut]

Hi everybody, I want to use Cassandra features but I can't work with
this server.

I have downloaded the server and I have started it, it goes well.

I download the SimpleCassie.php library and added it to my project.

Now I have added a Keyspace into the cassandra storage like this:

<Keyspace Name="Inventario">
<ColumnFamily CompareWith="UTF8Type" Name="Scaffale"/>
<ColumnFamily CompareWith="UTF8Type" Name="Oggetto"/>
<ColumnFamily CompareWith="UTF8Type" Name="Tipologie"/>
<!--
~ Strategy: The class that extends AbstractReplicationStrategy
~ determines how replicas are placed around the token ring.
~ Out of the box, Cassandra provides
~ org.apache.cassandra.locator.RackUnawareStrategy and
~ org.apache.cassandra.locator.RackAwareStrategy (place one
replica in
~ a different datacenter, and the others on different racks in
the same
~ one.)
-->

<ReplicaPlacementStrategy>org.apache.cassandra.locator.RackUnawareStrategy</
ReplicaPlacementStrategy>

<!-- Number of replicas of the data -->
<ReplicationFactor>1</ReplicationFactor>

<!--
~ EndPointSnitch: Setting this to the class that implements
~ AbstractEndpointSnitch, which lets Cassandra know enough
~ about your network topology to route requests efficiently.
~ Out of the box, Cassandra provides
org.apache.cassandra.locator.EndPointSnitch,
~ and PropertyFileEndPointSnitch is available in contrib/.
-->
<EndPointSnitch>org.apache.cassandra.locator.EndPointSnitch</
EndPointSnitch>
</Keyspace>

Now I have restarted the server and it create my keyspace.

I can't write anything into the database.

My test code is:

require_once('SimpleCassie.php');

$cassie = new SimpleCassie("127.0.0.1", "9160", 300);

if(!$cassie->isConnected())
throw new Exception('Couldn\'t connect to server');

$cassie->keyspace('Inventario')->cf('Oggetto')->key('fotocamera')-
>column('nome')->set('walter');

var_dump($cassie->keyspace('Inventario')->cf('Oggetto')-
>key('fotocamera')->get());

echo "FINE";

The VAR_DUMP directive is always null.

What I wrong?

Thanks for your help.
