Настройка Amazon ElastiCache со spymemcached на Java

Мне не удалось найти хороший учебник по Memcached в Amazon Cloud, и я новичок во всей этой штуке с кешированием. Я пытаюсь использовать memcached через службу Amazon ElastiCache и с клиентом spymemcached, чтобы фактически выполнять вызовы memcached.

Вот что я сейчас делаю на Java:

try {
        ConnectionFactoryBuilder connectionFactoryBuilder = new ConnectionFactoryBuilder();
        MemcachedClient memcachedClient = new MemcachedClient(
                connectionFactoryBuilder.build(),
                AddrUtil.getAddresses("<beginning of cache node end point grabbed from AWS Console>.cache.amazonaws.com:11211"));
        memcachedClient.set("test", 12, new Integer(12));
        System.out.println(memcachedClient.get("test"));
    } catch (IOException ioException) {
        ioException.printStackTrace();
    }

Я получаю следующее сообщение об ошибке:

У кого-нибудь есть идеи или опыт работы с этим? Спасибо!
