java - Elasticsearch - NoNodeAvailableException

Question

尝试使用 ES 2 的 Java API 连接到 Elasticsearch 2 时出现以下错误。这是代码:

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();

我能够在 transportClient.connectedNodes() 上获取我的 ES 节点，但是当我尝试添加新映射时，我遇到了 NoNodeAvailableException 异常。此代码适用于以前版本的 Elasticsearch。知道哪里出了问题吗？

感谢 the post he linked，@AndreiStefan 解决了我的问题.解决方案非常简单:

network.bind_host: 0
