NoNodeAvailableException [沒有配置的節點可用：[{＃transport＃-1} {...} {127.0.0.1} {127.0.0.1：9300}]]

Question

我知道這個問題已經得到了解決，但是我的所有嘗試都沒有辦法解決我的問題。

我剛剛安裝了elasticsearch並啟動它。 這里彈性的日志：

因此，Elastic完全運行並在端口9300上進行偵聽。

我的群集名稱是“my-application”。

由elasticsearch.yml確認：

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

並通過請求http：// localhost：9200 /來確認 ：

{
  "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"
}

這是我的Maven依賴項（彈性和客戶端的版本是對齊的）：

<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>

</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.21</version>
</dependency>

在這里我的java代碼：

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();
        }
    }
}

這給了我以下日志：

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

如果我嘗試在終端上執行此命令：

telnet 127.0.0.1 9300

我被提示，我只能輸入6個（不可見）字符和彈性控制台顯示（我輸入了azerty）：

這意味着9300端口是好的。

我不明白我做錯了什么。

Someowe可以幫幫我嗎？

Answer 1

我遇到了同樣的問題，我通過在elasticsearch.yml文件中添加transport.host: localhost屬性解決了上述問題。

添加后，它按預期工作。 我希望它能幫助這個主題的其他讀者。

Answer 2

好的，通過在我的問題的EDIT部分提供日志，我看到了一個安全異常。 所以我問自己：ES的哪個部分提供了安全方面。

答案是：X-Pack插件。

因此，為了檢查它是否真的是我的麻煩的來源，我使用此命令刪除它：
elasticsearch-plugin.bat remove x-pack

而且......它現在運作良好。 有厚！

這是我的Java代碼的結果：

{
    "took" : 21,
    "timed_out" : false,
    "_shards" : {
        "total" : 44,
        "successful" : 44,
        "failed" : 0
    },
    "hits" : {
        "total" : 306673,
        "max_score" : 1.0,
        "hits" : [{
                "_index" : ".kibana",
                "_type" : "config",
                "_id" : "5.0.0",
                "_score" : 1.0,
                "_source" : {
                    "buildNum" : 14438
                }
            },
            {
                "_index" : ".monitoring-alerts-2",
                "_type" : "doc",
                "_id" : "ygmbc6k0TpKdJP77OJeG9g_elasticsearch_cluster_status",
                "_score" : 1.0,
                "_source" : {[...]}
            },
            {
                "_index" : ".monitoring-data-2",
                "_type" : "kibana",
                "_id" : "60fef358-886c-43cb-9ef1-2257ccd2bcbb",
                "_score" : 1.0,
                "_source" : {[...]}
            },
            {[...]},
            {
                "_index" : ".monitoring-es-2-2017.05.11",
                "_type" : "index_stats",
                "_id" : "AVv3uOacGOX_5IPHNH_2",
                "_score" : 1.0,
                "_source" : {[...]}
            }
        ]
    }
}

我只需要查找此安全令牌部分，但這是另一個主題。

非常感謝@ andrei-stefan的幫助評論;）

Answer 3

我確實遇到了這個問題，對我來說，這是我的主機上運行的elasticsearch和IntelliJ pom.xml中的elasticsearch版本之間的版本

當我在兩端使用相同的版本時，它工作。 即我為我的主機下載了與我的客戶相同的版本然后它工作。

我修改了這個工作樣本來弄清楚：

https://github.com/spring-projects/spring-boot/tree/master/spring-boot-samples/spring-boot-sample-data-elasticsearch

Answer 4

我遇到過同樣的問題。 我的問題是我的/etc/elasticsearch.yml文件中的群集名稱與我在應用程序中引用的群集名稱不同。

我把名字匹配和賓果游戲！

Answer 5

如果您通過docker image運行彈性搜索。 然后通過下面的命令runt docker鏡像。

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”無法正常工作。

設置也應如下所示。 不要添加.put（“client.transport.sniff”，true）。

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

Answer 6

這是一個非常簡單的例子： https ： //github.com/EdersonJunior/ElasticSearch_Java

我的elasticsearch.yml文件是這樣的：

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

在屬性文件中設置9300主機端口非常重要。

Answer 7

使用ElasticSearch 6.3.1和Springboot2.0.0.RELASE並執行以下更改：

1. 使用以下代碼連接本地ElasticSearch服務器：

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

2. 更新ESeach .. \\ config \\ elasticsearch.yml cluster.name:farkalit-cluster

它將解決問題。

Answer 8

僅供參考，我正在嘗試使用7.2

org.elasticsearch.client:transport:5.5.1

並按照代碼連接到我的本地群集，同樣的錯誤彈出我的臉。

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;
    }

當我檢查ES控制台時，它已經警告我版本問題了

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]

所以我只是使用新版本來修復錯誤。

org.elasticsearch.client:transport:7.2.0

Answer 9

由於版本不匹配，可能會出現此錯誤。 檢入彈性搜索日志，它將指定有關要使用的elasticsearch客戶端的最低版本的更多詳細信息。 因此，要么升級客戶端jar，要么運行以下版本的elasticsearch
