提问by Jocker

I know that question has already been treated but with all my attemps, no way to fix my issue.

我知道这个问题已经得到处理，但我的所有尝试都无法解决我的问题。

I just installed elasticsearch and boot it. Here the log of elastic :

我刚刚安装了 elasticsearch 并启动了它。这是弹性的日志：

So, Elastic is fully running and listenning on the port 9300.

因此，Elastic 完全运行并侦听端口 9300。

My cluster name is "my-application".

我的集群名称是“my-application”。

Confirmed by elasticsearch.yml :

通过 elasticsearch.yml 确认：

# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: my-application
#

And also confirmed by requesting http://localhost:9200/:

并且还通过请求http://localhost:9200/ 确认：

{
  "name" : "xhkU1rX",
  "cluster_name" : "my-application",
  "cluster_uuid" : "ygmbc6k0TpKdJP77OJeG9g",
  "version" : {
    "number" : "5.4.0",
    "build_hash" : "780f8c4",
    "build_date" : "2017-04-28T17:43:27.229Z",
    "build_snapshot" : false,
    "lucene_version" : "6.5.0"
  },
  "tagline" : "You Know, for Search"
}

Here is my Maven dependencies (versions of elastic and client are aligned) :

这是我的 Maven 依赖项（弹性和客户端的版本是一致的）：

<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>transport</artifactId>
    <version>5.4.0</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-to-slf4j</artifactId>
    <version>2.7</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.21</version>
</dependency>

And here my java piece of code :

这里是我的 java 代码：

import java.net.InetAddress;
import java.net.UnknownHostException;
import java.util.Collections;

import org.elasticsearch.action.search.SearchResponse;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.transport.client.PreBuiltTransportClient;

public class Test {
    public static void main(String[] args) throws UnknownHostException {
        Settings clusterSettings = Settings.builder()
                .put("cluster.name", "my-application")
                .build();

        TransportClient transportClient = new PreBuiltTransportClient(clusterSettings)
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));

        try {
            SearchResponse response = transportClient
                    .prepareSearch()
                    .execute().actionGet();
            System.out.println(response.toString());
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            transportClient.close();
        }
    }
}

that gives me the following logs :

这给了我以下日志：

NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{nqelLN69RhSJabcb57_lWQ}{127.0.0.1}{127.0.0.1:9300}]]

If I try to execute this command on a terminal :

如果我尝试在终端上执行此命令：

telnet 127.0.0.1 9300

I'm prompted and I can enter only 6 (invisible) characters and elastic console display (I typed azerty) :

系统提示我，我只能输入 6 个（不可见）字符和弹性控制台显示（我输入 azerty）：

It means that the port 9300 is the good one.

这意味着端口 9300 是好的。

I don't understand what I am doing wrong.

我不明白我做错了什么。

Someowe can help me ?

有人可以帮助我吗？

OK, by providing you the logs in the EDIT part of my question, I saw a security exception. So I asked to myself : which part of ES is providing the security aspect.

好的，通过在我的问题的 EDIT 部分为您提供日志，我看到了一个安全异常。所以我问自己：ES 的哪一部分提供了安全方面。

The answer is : X-Pack plugin.

答案是：X-Pack 插件。

So to check if it's realy the source of my troubles, I removed it by using this command :
elasticsearch-plugin.bat remove x-pack

因此，为了检查它是否真的是我麻烦的根源，我使用以下命令将其删除：
elasticsearch-plugin.bat remove x-pack

And... it's working well now. Youhou !

而且……现在运行良好。悠悠！

I just have to look for this security token part but it's another topic.

我只需要寻找这个安全令牌部分，但它是另一个主题。

Many thanks to @andrei-stefan for the helping comment ;)

I have encountered same problem and i solved the mentioned issue by adding transport.host: localhostproperty in elasticsearch.ymlfile.

我遇到了同样的问题，我通过transport.host: localhost在elasticsearch.yml文件中添加属性解决了上述问题。

After adding it, it works as expected. I hope it will help other reader of this thread.

添加后，它按预期工作。我希望它能帮助这个线程的其他读者。

Just for reference, I am using 7.2while I was trying to use

仅供参考，我在尝试使用时使用的是7.2

org.elasticsearch.client:transport:5.5.1

and following code to connect to my local cluster, and same error popped into my face.

并按照代码连接到我的本地集群，同样的错误出现在我的面前。 

public static void main(String... args) {
        TransportClient client = getClient();
        SearchResponse response = client.prepareSearch("cars").execute().actionGet();
        System.out.println(response);
    }

    private static TransportClient getClient() {
        TransportClient client = null;
        try {
            client = new PreBuiltTransportClient(
                    Settings.builder().put("client.transport.sniff", true)
                            .put("cluster.name", "elasticsearch").build())
                    .addTransportAddress(new TransportAddress(InetAddress.getByName("127.0.0.1"), 9300));
            client.listedNodes();
        } catch (UnknownHostException e) {

        }
        return client;
    }

As I checked the ES console, it's already warned me of the version issues

当我检查 ES 控制台时，它已经警告我版本问题

exception caught on transport layer [Netty4TcpChannel{localAddress=/127.0.0.1:9300, remoteAddress=/127.0.0.1:62723}], closing connection
java.lang.IllegalStateException: Received handshake message from unsupported version: [5.0.0] minimal compatible version is: [6.8.0]

So I just use the new version to fix the error.

所以我只是使用新版本来修复错误。 

org.elasticsearch.client:transport:7.2.0

回答by rakesh

This error may come because of the version mismatch. Check in elastic search logs, it will specify more details about the minimum version of elasticsearch client to be used. So either upgrade client jar or run below versions of elasticsearch

由于版本不匹配，可能会出现此错误。检查弹性搜索日志，它将指定有关要使用的弹性搜索客户端最低版本的更多详细信息。因此，要么升级客户端 jar，要么在 Elasticsearch 的版本下运行

回答by powder366

I had exactly this issue, and for me it was the version between elasticsearch running on my host and the elasticsearch version in my IntelliJ pom.xml

我正是有这个问题，对我来说，它是在我的主机上运行的 elasticsearch 和我的 IntelliJ pom.xml 中的 elasticsearch 版本之间的版本

When I used the same version on both ends it worked. I.e. I downloaded the same version for my host as my client and then it worked.

当我在两端使用相同的版本时，它起作用了。即我为我的主机下载了与我的客户端相同的版本，然后它工作了。

I modified this working sample to figure it out:

我修改了这个工作示例来弄清楚：

回答by Chukwuemeka Inya

I had the same issue. My problem was that the cluster name in my /etc/elasticsearch.yml file was different from the cluster name I was referencing in my application.

我遇到过同样的问题。我的问题是 /etc/elasticsearch.yml 文件中的集群名称与我在应用程序中引用的集群名称不同。

I made the names match and bingo!

我让名字匹配和宾果游戏！

回答by arvin_v_s

if you are running the elastic search via docker image. then runt the docker image via below command.

如果您通过 docker 镜像运行弹性搜索。然后通过以下命令运行 docker 镜像。

docker run -p 9400:9200 -p 9401:9300 -e "http.host=0.0.0.0" -e "transport.host=0.0.0.0" -e "xpack.security.enabled=false" docker.elastic.co/elasticsearch/elasticsearch:5.2.2

-e "transport.host=127.0.0.1" did not work.

-e "transport.host=127.0.0.1" 不起作用。

Also settings should be as below. donot add the .put("client.transport.sniff", true).

设置也应如下所示。不要添加 .put("client.transport.sniff", true)。

Settings esSettings = Settings.builder()
            .put("cluster.name", EsClusterName)
            .build();

Here goes a very simple example: https://github.com/EdersonJunior/ElasticSearch_Java

这是一个非常简单的例子：https: //github.com/EdersonJunior/ElasticSearch_Java

My elasticsearch.yml file is like that:

我的 elasticsearch.yml 文件是这样的：

cluster.name: "elasticsearch"
node.name: "myNode"
network.host: 0.0.0.0
http.port: 9200

It's very important you setup the 9300 host port at properties file.

在属性文件中设置 9300 主机端口非常重要。

Use ElasticSearch 6.3.1 and Springboot2.0.0.RELASE and do the following changes:

使用 ElasticSearch 6.3.1 和 Springboot2.0.0.RELASE 并进行以下更改：

  1. Use the following code to connect the your local ElasticSearch Server:
  1. 使用以下代码连接您本地的 ElasticSearch 服务器：

Settings settings = Settings.builder().put("cluster.name", "farkalit-cluster").build(); transportClient = new PreBuiltTransportClient(settings).addTransportAddress(new TransportAddress(InetAddress.getByName("localhost"), 9300));

Settings settings = Settings.builder().put("cluster.name", "farkalit-cluster").build(); transportClient = new PreBuiltTransportClient(settings).addTransportAddress(new TransportAddress(InetAddress.getByName("localhost"), 9300));

  1. Update the ESeach..\config\elasticsearch.yml cluster.name: farkalit-cluster
  1. 更新 ESeach..\config\elasticsearch.yml cluster.name: farkalit-cluster

It will solves the problem.

它将解决问题。
