Elasticsearch - NoNodeAvailableException [英] Elasticsearch - NoNodeAvailableException

问题描述

尝试使用Java API for ES 2连接到Elasticsearch 2时，我收到以下错误。这是代码：

 设置设置= Settings.settingsBuilder（）。put（cluster.name，Receptor.clusterName）.build（）; 
 TransportClient transportClient = TransportClient.builder（）。settings（settings）.build（）; 
客户端c = null; 
 try {
 c = transportClient.addTransportAddress（new InetSocketTransportAddress（InetAddress.getByName（Receptor.es_ip），9300））; 
} catch（UnknownHostException e）{
 System.err.println（Util.getTimestampStr（）+UnknownHostException error。）; 
 e.printStackTrace（）; 
} 
 
 CreateIndexRequestBuilder createIndexRequestBuilder = c.admin（）。indexes（）。prepareCreate（indexName）; 
 createIndexRequestBuilder.addMapping（documentName，json）; 
 createIndexRequestBuilder.execute（）。actionGet（）; 
  

我可以在transportClient.connectedNodes（）上获取我的ES节点，但是当我尝试添加一个新映射，我得到 NoNodeAvailableException 异常。此代码与以前版本的Elasticsearch一起使用。任何想法是什么问题？

@AndreiStefan给了解决我的问题，感谢他链接的帖子。解决方案是直接的：

  network.bind_host：0 
  

谢谢你们。

I get the following error when trying to connect to Elasticsearch 2 using the Java API for ES 2. This is the code:

Settings settings = Settings.settingsBuilder().put("cluster.name", Receptor.clusterName).build();
TransportClient transportClient = TransportClient.builder().settings(settings).build();
Client c = null;
try {
     c = transportClient.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(Receptor.es_ip), 9300));
} catch (UnknownHostException e) {
     System.err.println(Util.getTimestampStr() + "UnknownHostException error.");
     e.printStackTrace();
}

CreateIndexRequestBuilder createIndexRequestBuilder = c.admin().indices().prepareCreate(indexName);
createIndexRequestBuilder.addMapping(documentName, json);
createIndexRequestBuilder.execute().actionGet();

I'm able to get my ES node on the transportClient.connectedNodes() but when I try to add a new mapping I get the NoNodeAvailableException exception. This code worked with previous versions of Elasticsearch. Any idea of what's wrong?

解决方案

@AndreiStefan gave the solution to my problem thanks to the post he linked. The solution was as straightforward as:

network.bind_host: 0
