spymemcached client java pour Couchbase

Question

Je suis en train d'écrire un simple client java pour interagir avec Couchbase en utilisant la bibliothèque spymemcached (ma condition, je ne peux pas utiliser sdk Couchbase)

Mon code ressemble ci-dessous -

AuthDescriptor ad = new AuthDescriptor(new String[] { "PLAIN" }, 
    new PlainCallbackHandler(
      "****", "****")); 

MemcachedClient client = new MemcachedClient(
    new ConnectionFactoryBuilder() 
    .setProtocol(ConnectionFactoryBuilder.Protocol.BINARY) 
    .setAuthDescriptor(ad) 
    .build(), 
    AddrUtil.getAddresses(Arrays.asList("127.0.0.1:11211"))); 

// Store a value (async) for one hour 
client.set("someKey", 3600, "someValue"); 
client.set("otherKey", 3600, 100L); 
client.set("1", 3600, 1); 
client.set("2", 3600, 2); 

// Retrieve a value. 
Object myObject = client.get("someKey"); 
System.out.println(myObject); 

Map<String, Object> someKey = client.getBulk("someKey"); 
for (Map.Entry<String, Object> entry : someKey.entrySet()) { 
    System.out.println(entry.getKey()); 
    System.out.println(entry.getValue()); 
} 

Collection<SocketAddress> servers = client.getAvailableServers(); 
System.out.println(servers); 

client.shutdown(); 

Je Couchbase en serveur et en cours d'exécution dans mon localhost et quand je lance le code ci-dessus, je reçois l'erreur suivante -

J'ai essayé aussi la connexion aux localhos t instance en utilisant telnet et la commande de statistiques a couru mais a obtenu cette erreur - SERVER_ERROR unauthorized, null bucket

Appréciez toutes les entrées pour résoudre ce problème!

Ce problème se produit avec Couchbase Server 5.0 version bêta 2, lorsque j'ai essayé avec une version stable Couchbase Server 4.6.0 cela fonctionne très bien.
