弹性搜索和隧道：我可以使用浏览器（google_chrome）连接到elesticsearch，但不能与JAVA api连接 [英] elasticsearch and tunnel : i can connect to elesticsearch using browser(google_chrome) but not with JAVA api

问题描述

我有这个错误：

org.elasticsearch.client.transport.NoNodeAvailableException：没有配置的节点可用

解决方案

p>我已经尝试在我的环境中重新创建配置，并设法使用Elasticsearch（创建了一个索引）。以下是如何进行的：

• 为Elasticsearch 9300和9200端口配置Putty隧道


• 您需要打开SSH连接并确保已连接


• 您可以查看SSH事件日志
  

代码看起来像这样

  public class App 
 {
 public static void main（String [] args）throws Exception 
 {
设置设置= ImmutableSettings.settingsBuilder（）。 
 put（cluster.name，my-cluster）。build（）; 
 TransportClient client = new TransportClient（settings）
 .addTransportAddress（
 new InetSocketTransportAddress（
localhost，9093））; 
 CreateIndexResponse rs = client.admin（）。indexes（）。create（new CreateIndexRequest（tunnelingindex））actionGet（）; 
 System.out.println（rs.isAcknowledged（））; 
 client.close（）; 
} 
} 
  

代码创建一个名为 tunnelingindex
如果仍然不适合您，我认为您可能有一个与隧道或弹性搜索无关的问题。

希望我有成功的帮助。

my cluster it's not in the same network, and there is a tunnel between my pc and the server.

i have got this error :

org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available

解决方案

I have tried to recreate your configuration on my environment and managed to work with Elasticsearch (created an index). Here is how it goes:

• Configure Putty tunneling for Elasticsearch 9300 and 9200 ports
• After configuring you'll need to open the SSH connection and make sure it is connected
• You may look at the SSH event log here is a link on how to do it

The code looks like this

public class App 
{
    public static void main( String[] args ) throws Exception
    {
        Settings settings = ImmutableSettings.settingsBuilder().
                                              put("cluster.name", "my-cluster").build();
        TransportClient client = new TransportClient(settings)
                                    .addTransportAddress(
                                            new InetSocketTransportAddress(
                                                    "localhost", 9093));
        CreateIndexResponse rs = client.admin().indices().create(new CreateIndexRequest("tunnelingindex")).actionGet();
        System.out.println(rs.isAcknowledged());
        client.close();
    }
}

The code creates an index named tunnelingindex If it still do not work for you, I think that you may have an issue which is not related to tunneling or Elasticsearch.

Hope I have managed to help.
