与远程弹性搜索群集的连接失败

我正尝试使用传输客户端连接到远程弹性搜索群集。与远程弹性搜索群集的连接失败

public class AuthenticationExample { 

    public static void main(String[] args) throws Exception { 
     if (args.length != 4) { 
      System.out.println("Usage :\njava -jar jarFile.jar clusterName hostIP port index"); 
      System.exit(0); 
     } 
     String clusterName = args[0]; 
     String hostName = args[1]; 
     int port = Integer.parseInt(args[2]); 
     String index = args[3]; 
     Settings settings = Settings.builder() 
       .put("cluster.name", clusterName).build(); 
     TransportClient esClient = new PreBuiltTransportClient(settings) 
       .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(hostName), port)); 
     esClient.threadPool().getThreadContext().putHeader("Authorization", "Basic " + Base64.encodeBase64("user:password".getBytes())); 
     System.out.println("Initialized successfully."); 
     boolean isIndexExists = false; 
     isIndexExists = esClient.admin().indices().prepareExists(index).execute().actionGet().isExists(); 
     if (isIndexExists) { 
      System.out.println("Is Index " + index + " Exists? " + isIndexExists); 
     } else { 
      System.out.println("Index " + index + " does not exist"); 
     } 
    } 
}

当我运行上面的代码，如

Java的罐子jarFile.jar CLUSTERNAME XXX.XXX.XXX.XXX 9300 INDEXNAME

我收到以下异常 NoNodeAvailableException [无配置的节点可用：...

此外，当我打采用端点，

卷曲-XGET -u用户名：密码http://XXX.XXX.XXX.XXX:9200

我得到的响应如下，

{ 
    "name" : "XfJq4ed", 
    "cluster_name" : "elasticsearch", 
    "cluster_uuid" : "26yoM76iT8i-eo8k0E8y4g", 
    "version" : { 
    "number" : "5.4.0", 
    "build_hash" : "780f8c4", 
    "build_date" : "2017-04-28T17:43:27.229Z", 
    "build_snapshot" : false, 
    "lucene_version" : "6.5.0" 
    }, 
    "tagline" : "You Know, for Search" 
}

请给我一个解决方案。谢谢

你是否允许HTTP模块？

你可以在这里看到avalaible选项：https://www.elastic.co/guide/en/elasticsearch/reference/5.4/modules-http.html

既然是远程服务器，我只知道用户名和密码。我不知道HTTP模块。任何其他方式从java客户端做？ – Janaarthan

因此，如果它是远程服务器，可能会启用http。请检查此链接： https://www.elastic.co/guide/en/elasticsearch/reference/5.4/modules-network.html 'discovery.zen.ping.unicast.hosts' - 默认为[“127.0.0.1”，“[:: 1]”] – Ansaldos
