spymemcached Java-Client für Couchbase

Question

Ich versuche, einen einfachen Java-Client zu schreiben, mit Couchbase mit spymemcached Bibliothek zur Interaktion

Mein Code sieht unten (meine Forderung, ich kann nicht Couchbase sdk verwenden) wie -

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(); 

ich habe in meinem localhost Couchbase Server und läuft und wenn ich den obigen Code ausführen, bekomme ich folgende Fehler -

ich versuchte auch, den localhos Verbindungs T-Instanz mit Telnet und ran stats Befehl, aber habe diesen Fehler -

Dieses Problem tritt bei Couchbase Server 5.0 Beta 2 Version auf, als ich es mit einer stabilen Version Couchbase Server 4.6.0 versuchte funktioniert es gut.
