Couchbase: java-клиент не создает документ на сервере

Я новичок в Couchbase, я копирую/вставляю первый пример кода в (http://www.couchbase.com/communities/java/getting-started) в моем проекте Eclipse, но когда я запускаю его и проверяю сервер, я не могу найти документ, ниже вывод консоли:

и вот мой класс Java:

public class Test_ {

public static void main(String[] args) throws Exception {

// (Subset) of nodes in the cluster to establish a connection
List hosts = Arrays.asList(new URI("http://localhost:8091/pools"));

// Name of the Bucket to connect to
String bucket = "trust";

// Password of the bucket (empty) string if none
String password = "HIDDEN";

// Connect to the Cluster
CouchbaseClient client = new CouchbaseClient(hosts, bucket, password);

// Store a Document
client.set("33", "test my java code").get();

// Retreive the Document and print it
//System.out.println(client.get("33"));

// Shutting down properly
client.shutdown();
}
}
