我知道这个问题已经得到了处理，但我的所有尝试都无法解决我的问题。
我刚刚安装了elasticsearch并启动它。这里是弹性的日志：

因此，Elastic正在运行并在端口9300上进行侦听。
我的群集名称是＆＃34; my-application＆＃34;。
由elasticsearch.yml确认：
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: my-application
#
并通过请求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"
}
这是我的Maven依赖项（弹性和客户端的版本对齐）：

System.out.println(response.toString());
} catch (Exception e) {

} finally {

}
}
给了我以下日志：

这意味着端口9300是好的。
我不明白我做错了什么。
Someowe可以帮助我吗？

我遇到了同样的问题，我通过在 elasticsearch.yml 文件中添加transport.host: localhost属性解决了上述问题。
添加后，它按预期工作。我希望它能帮助这个主题的其他读者。

仅供参考，我在尝试使用
时正在使用 7.2org.elasticsearch.client:transport:5.5.1
和下面的代码连接到我的本地集群，同样的错误突然冒出。
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;
}
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]
所以我只使用新版本来修复错误。
org.elasticsearch.client:transport:7.2.0

好的，通过在我的问题的EDIT部分提供日志，我看到了一个安全例外。 所以我问自己：ES的哪个部分提供了安全方面。
答案是：X-Pack插件。
因此，为了检查它是否真的是我的麻烦的来源，我使用此命令将其删除：
elasticsearch-plugin.bat remove x-pack
而且......它现在运作良好。 Youhou！
以下是我的Java代码的结果：
{
"took" : 21,
"timed_out" : false,
"_shards" : {
"total" : 44,
"successful" : 44,
"failed" : 0

}
]
}
}
我只需要查找此安全令牌部分，但它是另一个主题。
非常感谢@ andrei-stefan的帮助评论;）

我确实遇到过这个问题，对我来说，这是我的主机上运行的elasticsearch和IntelliJ pom.xml中的elasticsearch版本之间的版本
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，然后就可以了。
我修改了这个工作样本来弄明白：

我有同样的问题。我的问题是我的/etc/elasticsearch.yml文件中的群集名称与我在我的应用程序中引用的群集名称不同。
我把名字命名为宾果游戏！

如果您通过docker image运行弹性搜索。 然后通过下面的命令来破坏码头图像。
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”无效。
此外，设置应如下所示。不要添加.put（“client.transport.sniff”，true）。
Settings esSettings = Settings.builder()
.put("cluster.name", EsClusterName)
.build();

这是一个非常简单的例子：https://github.com/EdersonJunior/ElasticSearch_Java
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
在属性文件中设置9300主机端口非常重要。

使用ElasticSearch 6.3.1和Springboot2.0.0.RELASE并进行以下更改：
设置设置= Settings.builder（）。put（“ cluster.name”，“ farkalit-cluster”）。build（）; transportClient =新的PreBuiltTransportClient（设置）.addTransportAddress（新的TransportAddress（InetAddress.getByName（“ localhost”），9300））;
它将解决问题。

此错误可能是由于版本不匹配而引起的。签入弹性搜索日志，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，要么在弹性搜索版本以下运行
