如何使用Elasticsearch Node Client Java连接到远程服务器

Question

我正在尝试使用Elasticsearch Java NodeBuilder Client连接到我的服务器.但是我没有看到任何指定我的服务器地址和端口的选项(就像我们可以在Transport Client中一样使用addNewTransportAddress("serveraddress", port)).如何让Node Client连接到我的服务器？代码如下,我在哪里提到要连接的服务器地址？

//On Startup
Node node = nodeBuilder()
        .clusterName("elasticsearch")
        .data(false) //No shards allocated; or can set client to true
        .client(true) //No shards allocated; or can set data to false
        .node();

//Node Client
Client client = node.client();

//Get API       
GetResponse response = client.prepareGet("indexname", "type", "id")
        .execute()
        .actionGet();

System.out.println("----------------Index Output Begin----------------");
System.out.println("Index Name: " + response.getIndex());
System.out.println("Type: " + response.getType());
System.out.println("Document ID: " + response.getId());
System.out.println("Document Version: " + response.getVersion());
System.out.println("Source: " + response.getSourceAsString());

节点客户端基于多播.客户端和节点之间的网络必须位于具有多播启用的网络中.然后客户端将根据群集名称"发现"节点.

如果需要连接到远程服务器(通过指定IP地址),则必须使用传输客户端.

Settings settings = ImmutableSettings.settingsBuilder()
        .put("cluster.name", "myClusterName").build();
Client client = new TransportClient(settings)
        .addTransportAddress(new InetSocketTransportAddress("host1", 9300))
        .addTransportAddress(new InetSocketTransportAddress("host2", 9300));
