更新:现在我真的很困惑.我只是在日食中按了3次.2次收到上述错误.1次搜索工作!?? 全新的Centos 6.5 vps,全新的jdk安装.然后安装了elasticsearch,没有做任何其他的事情.

可能的问题:

  1. 错误的端口,如果你使用Java或Scala客户端,正确的端口是9300,不是9200
  2. 错误的群集名称,请确保您在代码中设置的群集名称与您设置的cluster.name相同 $ES_HOME/config/elasticsearch.yml
  3. sniff选项,设置client.transport.sniff为true但无法连接到ES群集的所有节点也会导致此问题.ES doc在这里解释了原因.

Ari*_*tra 34

Elasticsearch设置在$ES_HOME/config/elasticsearch.yml.在那里,如果cluster.name设置被注释掉,则意味着ES将采用任何群集名称.所以,在你的代码中,cluster.name因为"elastictest"可能是问题.试试这个:

Client client = new TransportClient()
                .addTransportAddress(new InetSocketTransportAddress(
                        "143.79.236.xxx",
                        9300));

  • 谢谢.我设置了cluster.name但忘记在创建TransportClient时将其添加到"设置"中. (2认同)
  • org.elasticsearch.client.transport.TransportClient是一个抽象类。您如何通过键入new TransportClient（）获得实例？ (2认同)

小智 14

您应该检查节点的端口,您可以使用head来完成.这些端口不相同.例,

您可以打开的Web URL是localhost:9200节点的端口9300,因此如果您使用9200该端口作为端口,则所有已配置的节点都不可用.

遇到类似问题，这里是解决方案

例子 ：

  1. 在 elasticsearch.yml 中添加以下属性

    cluster.name: production
node.name: node1
network.bind_host: 10.0.1.22
network.host: 0.0.0.0
transport.tcp.port: 9300
    Run Code Online (Sandbox Code Playgroud)

  2. 在 Java Elastic API for Bulk Push 中添加以下内容（只是一个代码片段）。对于IP地址添加弹性搜索机的公共IP地址

    Client client;
BulkRequestBuilder requestBuilder;
try {
    client = TransportClient.builder().settings(Settings.builder().put("cluster.name", "production").put("node.name","node1")).build().addTransportAddress(
    new InetSocketTransportAddress(InetAddress.getByName(""), 9300));
    requestBuilder = (client).prepareBulk();
} 
catch (Exception e) {
}

  3. 打开 9200,9300 的防火墙端口

就我而言，这是版本的差异。如果您查看elasticsearch集群中的日志，将会看到。

Elasticsearch日志

我正在使用Elasticsearch客户端并传输5.1.1版。我的Elasticsearch集群版本为6。因此，我将库版本更改为5.4.3。

我花了几天时间一起解决这个问题。我知道已经晚了但这可能会有所帮助：

我通过更改以下版本的兼容/稳定版本解决了这个问题：

Spring boot: 2.1.1
Spring Data Elastic: 2.1.4
Elastic: 6.4.0 (default)

您无需提及 Elastic 版本。默认情况下为 6.4.0。但如果你想添加特定版本。在属性标签内使用以下代码片段并使用 Spring Boot 和 Spring Data 的兼容版本（如果需要）

<properties>

另外，我在 ElasticConfiguration 中使用了 Rest High Level 客户端：

@Value("${elasticsearch.host}")
public String host;

@Value("${elasticsearch.port}")
public int port;

@Bean(destroyMethod = "close")
public RestHighLevelClient restClient1() {
    final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
    RestClientBuilder builder = RestClient.builder(new HttpHost(host, port));
    RestHighLevelClient client = new RestHighLevelClient(builder);
    return client;
    }
}
Run Code Online (Sandbox Code Playgroud)

重要提示：Elastic 使用 9300 端口在节点之间进行通信，9200 作为 HTTP 客户端。在应用程序属性中：

elasticsearch.host=10.40.43.111
elasticsearch.port=9200
