我對彈性搜索概念非常陌生。我正在嘗試使用彈性搜索來構建一個簡單的應用程序。在彈性搜索中沒有可用的節點例外
public class App
{
public static void main(String[] args)
{
try {
TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
ElasticOperations.addDocToIndex(client, ElasticUtility.getJsonMap("Sandesha", "male", "[email protected]", "Hassan"));
System.out.println("Doc added");
client.close();
} catch (UnknownHostException e) {
e.printStackTrace();
}
}
}
但是,當試圖運行這個程序時,我得到NoNodeAvailableException
。
異常在線程 「主」 NoNodeAvailableException [配置的節點都不是可用的:[{#運輸#-1} {w1bSLAN-TFWUHE1PA3qDeQ} {本地主機} {127.0.0.1:9300}]] 在有機.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:347) at org.elasticsearch.client.transport.TransportClientNodesService.execute(TransportClientNodesService.java:245) at org.elasticsearch.client.transport.TransportProxyClient.execute (TransportProxyClient.java:59) at org.elasticsearch.client.transport.TransportClient.doExecute(TransportClient.java:363) at org.elasticsearch.client.support.AbstractClient.execute(Abst ractClient.java:408) at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:80) at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:54) at com.sandesha.elasticsearch。 Elastic.ElasticOperations.addDocToIndex(ElasticOperations.java:11) 在com.sandesha.elasticsearch.Elastic.App.main(App.java:27)
請幫我解決這個問題。 我ElasticOperations
類,
public class ElasticOperations {
public static void addDocToIndex(TransportClient client, Map<String,Object> jsonMap)
{
client.prepareIndex("customers", "personal").setSource(jsonMap).execute().actionGet();
}
}
而且我ElasticUtility
類是什麼樣子,
public class ElasticUtility {
public static Map<String, Object> getJsonMap(String name, String gender, String email, String city)
{
Map<String,Object> jsonMap = new HashMap<String, Object>();
jsonMap.put("name", name);
jsonMap.put("gender", gender);
jsonMap.put("email", email);
jsonMap.put("city", city);
return jsonMap;
}
}
謝謝。
您可以從終端連接到彈性還是使用感應? – sourabh1024
我可以通過終端連接。它運行在9200端口上 –
