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，没有做任何其他事情。

更新：运行./bin/elasticsearch console

- elasticsearch.yml中的群集配置 -

cluster.name: elastictest

答案 0 :(得分：34)

Elasticsearch设置位于$ES_HOME/config/elasticsearch.yml。在那里，如果注释掉cluster.name设置，则意味着ES将采用任何群集名称。因此，在您的代码中，cluster.name和"elastictest"可能是问题所在。试试这个：

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

答案 1 :(得分：31)

可能的问题：

  1. 错误的端口，如果您使用Java或Scala客户端，正确的端口是9300，而不是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在$ES_HOME/config/elasticsearch.yml
    3. 中设置的cluster.name相同
  3. 嗅探选项，将client.transport.sniff设置为true但无法连接到ES群集的所有节点也会导致此问题。 ES doc here解释了原因。

答案 2 :(得分：14)

您应该检查节点的端口，您可以使用head进行检查。 这些端口不相同。例如，

您可以打开的网址是localhost:9200， 但节点的端口为9300，因此如果您使用9200作为端口，则所有已配置的节点都不可用。

答案 3 :(得分：4)

面临类似的问题，这是解决方案

示例：

  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

  2. 在批量推送的Java Elastic API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. 打开防火墙端口9200,9300

答案 4 :(得分：4)

NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{UfB9geJCR--spyD7ewmoXQ}{192.168.1.245}{192.168.1.245:9300}]]

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

[node1] exception caught on transport layer [NettyTcpChannel{localAddress=/192.168.1.245:9300, remoteAddress=/172.16.1.47:65130}], closing connection
java.lang.IllegalStateException: Received message from unsupported version: [5.0.0] minimal compatible version is: [5.6.0]

我正在使用elasticsearch客户端和传输版本5.1.1。我的Elasticsearch集群版本为6。所以我将库版本更改为5.4.3。

答案 5 :(得分：3)

为了完成起见，这里是使用InetSocketTransportAddress提供的适当静态方法创建传输客户端的代码段：

    Client esClient = TransportClient.builder()
        .settings(settings)
        .build()
        .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("143.79.236.xxx"), 9300));

答案 6 :(得分：3)

如果上述建议不适合您，请将日志框架配置（log4j，logback ...）的日志级别更改为 INFO 。然后重新检查输出。

记录器可能隐藏了以下消息：

HH

（在上面的示例中，ElasticSearch中有X-Pack插件需要身份验证）

答案 7 :(得分：2)

其他用户遇到此问题。

如果在运行Spring Boot＆lt; 2版本时运行较新的ElasticSearch（5.5或更高版本），则可能会出现此错误。

建议使用REST客户端，因为不推荐使用Java客户端。

其他解决方法是升级到Spring Boot 2，因为它应该是兼容的。

有关详细信息，请参阅https://discuss.elastic.co/t/spring-data-elasticsearch-cant-connect-with-elasticsearch-5-5-0/94235。

由于大多数答案似乎都已过时，因此这是对我有用的设置：

  • Elasticsearch版本：：在Docker上运行的7.2.0（OSS）
  • Java版本： JDK-11

}

设置：

cluster.name: production
node.name: node1
network.host: 0.0.0.0
transport.tcp.port: 9300
cluster.initial_master_nodes: node1

由于不赞成使用PreBuiltTransportClient，因此您应将RestHighLevelClient用于Elasticsearch-Version 7.3.0：https://artifacts.elastic.co/javadoc/org/elasticsearch/client/elasticsearch-rest-high-level-client/7.3.0/index.html

检查你的elasticsearch.yml，“transport.host”属性必须是“0.0.0.0”而不是“127.0.0.1”或“localhost”

答案 10 :(得分：1)

我花了几天时间解决这个问题。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/稳定版本解决了该问题：

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

行家：

<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.1.RELEASE</version>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-elasticsearch</artifactId>
<version>2.1.4.RELEASE</version>
</dependency>

<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
</dependency>

您无需提及弹性版本。默认情况下为6.4.0。但是，如果要添加特定版本。在属性标签内使用以下代码片段，并使用兼容版本的Spring Boot和Spring Data（如果需要）

<properties>
<elasticsearch.version>6.8.0</elasticsearch.version>
</properties>

此外，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;
    }
}

重要说明： 弹性使用9300端口在节点之间进行通信，并使用9200作为HTTP客户端。在应用程序属性中：

elasticsearch.host=10.40.43.111
elasticsearch.port=9200

spring.data.elasticsearch.cluster-nodes=10.40.43.111:9300 (customized Elastic server)
spring.data.elasticsearch.cluster-name=any-cluster-name (customized cluster name)

在Postman中，您可以使用：http://10.40.43.111:9200/[indexname]/_search

答案 12 :(得分：0)

这意味着我们无法实例化ES transportClient并抛出此异常。有几种可能性会导致此问题。

  • 群集名称不正确。因此打开ES_HOME_DIR/config/elasticserach.yml文件并检查群集名称值或使用此命令：curl -XGET 'http://localhost:9200/_nodes'
  • 验证端口9200是http端口，但elasticsearch服务正在使用tcp端口9300 [默认]。因此，请验证端口是否未被阻止。

  • 身份验证问题：在transportClient的上下文中设置标头以进行身份​​验证：

    client.threadPool().getThreadContext()
  .putHeader("Authorization", "Basic " + encodeBase64String(basicHeader.getBytes()));

如果您仍然遇到此问题，请添加以下属性：

put("client.transport.ignore_cluster_name", true)

以下基本代码对我来说很好：

Settings settings = Settings.builder()
            .put("cluster.name", "my-application").put("client.transport.sniff", true).put("client.transport.ignore_cluster_name", false).build();
    TransportClient client = new PreBuiltTransportClient(settings).addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));

如果您正在使用Java Transport Client 1.检查9300是否可以访问/打开。 2.检查节点和群集名称，这应该是正确的，您可以通过在浏览器中键入ip：port来检查节点和群集名称。 3.检查您的jar版本和Es安装版本。

更改版本的ElasticSearch对我有用。

答案 15 :(得分：0)

这个在ES 1.7.5中对我有用：

import org.elasticsearch.action.index.IndexResponse;
import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.ImmutableSettings;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.common.xcontent.XContentBuilder;

public static void main(String[] args) throws IOException  {
    Settings settings = ImmutableSettings.settingsBuilder()
            .put("client.transport.sniff",true)
            .put("cluster.name","elasticcluster").build();

    Client client = new TransportClient(settings)
            .addTransportAddress(new InetSocketTransportAddress("[ipaddress]",9300));
    XContentBuilder builder = null;
    try {
        builder = jsonBuilder().startObject().field("user", "testdata").field("postdata",new Date()).field("message","testmessage")
                .endObject();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    System.out.println(builder.string());

    IndexResponse response = client.prepareIndex("twitter","tweet","1").setSource(builder).execute().actionGet();

    client.close();

}

如果上面的答案不起作用，我知道我来晚了，我建议在elasticsearch终端中检查日志。我发现错误消息说我需要将版本从5.0.0-rc1更新为6.8.0，我通过将maven依赖项更新为以下内容来解决了该问题：

<dependency>
  <groupId>org.elasticsearch</groupId>
  <artifactId>elasticsearch</artifactId>
  <version>6.8.0</version>
</dependency>
  <dependency>
  <groupId>org.elasticsearch.client</groupId>
  <artifactId>transport</artifactId>
  <version>6.8.0</version>
</dependency>

这也更改了我的代码，因为InetSocketTransportAddress已过时。我必须将其更改为TransportAddress 

TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)
               .addTransportAddress(new TransportAddress(InetAddress.getByName(host), port));

您还需要将此文件添加到您的 config / elasticsearch.yml 文件中（使用您的主机地址）

transport.host: localhost

我有同样的问题。我的问题是依赖项的版本与elasticsearch版本冲突。检查ip：9200中的版本并使用与其匹配的依赖项版本

答案 18 :(得分：-1)

您应该检查日志 如果您看到如下图 “ stacktrace”：[“ java.lang.IllegalStateException：从不支持的版本收到的消息：[6.4.3]最小兼容版本是：[6.8.0]”

您可以检查此链接 https://discuss.elastic.co/t/java-client-or-spring-boot-for-elasticsearch-7-3-1/199778 您必须显式声明es版本。
