spymemcached 자바 클라이언트 실패가 제대로 작동하지 취급 : membase 서버

Question

를 내가 membase 서버를 주석에 대한 aspymemcached 자바 클라이언트를 사용하고 있습니다 :

public static void main(String[] args) throws Exception{ 
     MemcachedClient client = null; 
     try { 
      URI server1 = new URI("http://192.168.100.111:8091/pools"); //primary 
      URI server2 = new URI("http://127.0.0.1:8091/pools"); //secondry 
      ArrayList<URI> serverList = new ArrayList<URI>(); 
      serverList.add(server1); 
      serverList.add(server2); 
      client = new MemcachedClient(serverList, "bucketName", ""); 
      client.set("spoon", 50000, "Hello World!"); //after this line i am going to down server 1 (192.168.100.111:8091/pools) 
      Thread.sleep(35000); 
      Object obj = client.get("spoon"); // on excetuting this line value should returns from server 2 
     } catch (Exception e) { 
      log.error("Exception in initializing membase connection:" + e.getMessage(), e); 
     } 
} 

나는 2 membase 서버가 복제를들이받은 있습니다. 이제 기본 (서버 1) 노드가 다운 후 클라이언트가 보조 노드 (서버 2)에서 값을 읽는되지 않고, 나는 다음과 같은 오류가 무엇입니까가는 경우 :

내 예상되는 동작입니다

는, 클라이언트가 secondry 서버 (서버 2)에서 값을 읽어야을 주 서버를 다시 연결해야합니다.
