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中使用addNewTransportAddress("serveraddress", port))
那样。。如何让Node Client连接到我的服务器?代码如下所示,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。然后客户将发现"节点基于群集名称。
如果您需要连接到远程服务器(通过指定IP地址),则必须使用transport client。
Settings settings = ImmutableSettings.settingsBuilder()
.put("cluster.name", "myClusterName").build();
Client client = new TransportClient(settings)
.addTransportAddress(new InetSocketTransportAddress("host1", 9300))
.addTransportAddress(new InetSocketTransportAddress("host2", 9300));

当我使用ImmutableSettings时,我得到了"ImmutableSettings cannot be resolved"
。
我的代码是:
Node node =nodeBuilder()
.settings(ImmutableSettings.settingsBuilder().put("path.home", "/home/amit/elasticsearch-2.1.0/bin"))
.client(true)
.node();
Client client = node.client();
