ElasticSearch 2.0传输客户机 - 无节点可用异常 [英] ElasticSearch 2.0 Transport Client - No Node Available exception

问题描述

[使用ElasticSearch 2.0版]

在etc / hosts文件中，esnode映射到IP地址（ES运行的其他一些机器） p>

192.168.2.219 esnode

运输客户端代码是::

  public Client getClient（）{
 if（（this.client == null））{
 try {
设置设置=设置。 settingsBuilder（）
 .put（cluster.name，myclustername）。build（）; 
 TransportClient tClient = TransportClient.builder（）。settings（settings）.build（）; 
 String [] nodes =esnode：9300.split（COMMA）; 
（String node：nodes）{
 String [] hostPort = node.split（COLON）; 
 
 tClient.addTransportAddress（new InetSocketTransportAddress（
 InetAddress.getByName（hostPort [0]），Integer.parseInt（hostPort [1]）））; 
} 
 this.client = tClient; 
 
} catch（Exception e）{
 e.printStackTrace（）; 
} 
} 
 return this.client; 
} 
  

此客户端代码运行，但执行以下代码时：
此.getClient（）。prepareGet（indexName，typeName，String.valueOf（id））。get（）;

抛出异常：

  NoNodeAvailableException [没有配置节点可用：[]] 
在org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable（TransportClientNodesService.java:280）
在org.elasticsearch.client.transport.TransportClientNodesService.execute（TransportClientNodesService.java ：197）
在org.elasticsearch.client.transport.support.TransportProxyClient.execute（TransportProxyClient.java:55）
在org.elasticsearch.client.transport.TransportClient.doExecute（TransportClient.java:272 ）
在org.elasticsearch.client.support.AbstractClient.execute（AbstractClient.java:347）

在org.elasticsearch.action.ActionRequestBuilder.execute（ActionRequestBuilder.java:59）
在org.elasticsearch.action.ActionRequestBuilder.g et（ActionRequestBuilder.java:67）
  

我也尝试使用IPAddress而不是主机名。如果

esnode映射到127.0.0.1

可以有人帮助...

解决方案

设置弹性搜索主机ip地址到elastic.arch.yml中的network.host值

network.host：es_host_ip

这是解决TransportClient NoNodeAvailableException问题。

[Using ElasticSearch version 2.0]

In etc/hosts file "esnode" is mapped to IP address(some other machine where ES is running) as shown

192.168.2.219 esnode

The Transport Client code is ::

public Client getClient() { 
    if ((this.client == null)) { 
        try { 
            Settings settings = Settings.settingsBuilder() 
                    .put("cluster.name", "myclustername").build(); 
            TransportClient tClient = TransportClient.builder().settings(settings).build(); 
            String[] nodes = "esnode:9300".split(COMMA); 
            for (String node : nodes) { 
                String[] hostPort = node.split(COLON); 

                tClient.addTransportAddress(new InetSocketTransportAddress( 
                        InetAddress.getByName(hostPort[0]), Integer.parseInt(hostPort[1]))); 
            } 
            this.client = tClient; 

        } catch (Exception e) { 
            e.printStackTrace(); 
        } 
    } 
    return this.client; 
} 

This client code runs but when executing the below code : this.getClient().prepareGet(indexName, typeName, String.valueOf(id)).get();

The exception is thrown:

NoNodeAvailableException[None of the configured nodes are available: []] 
        at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:280) 
        at org.elasticsearch.client.transport.TransportClientNodesService.execute(TransportClientNodesService.java:197) 
        at org.elasticsearch.client.transport.support.TransportProxyClient.execute(TransportProxyClient.java:55) 
        at org.elasticsearch.client.transport.TransportClient.doExecute(TransportClient.java:272) 
        at org.elasticsearch.client.support.AbstractClient.execute(AbstractClient.java:347) 
        at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:85) 
        at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:59) 
        at org.elasticsearch.action.ActionRequestBuilder.get(ActionRequestBuilder.java:67) 

I have also tried using IPAddress instead of host name. The above code runs properly if

esnode is mapped to 127.0.0.1

Can somebody help...

解决方案

Setup elasticsearch host ip address to network.host value in elasticsearch.yml

network.host: es_host_ip

This is solve TransportClient NoNodeAvailableException issue.
