java - 无法使用 Java API 连接到 ElasticSearch 服务器

标签 java elasticsearch

我正在尝试使用 Java API 连接到 ElasticSearch 服务器。我使用 Elasticsearch 服务来启动/停止和 Elasticsearch 头来可视化集群。集群/节点处于 Activity 状态，REST API 通过 curl 在 9200 上运行良好。我已经阅读了几乎所有关于这个主题的帖子，但我无法让它工作，以下是我的详细信息:

这些我都试过了:

  1. 在 TransportClient 中使用 localhost、devhost1、127.0.0.1 或网络上的实际 IP
  2. 在 config.yaml 中取消注释 IP 属性并放入 127.0.0.1(服务器)
  3. 检查端口 9300 是否可用。

...9200/_cluster/nodes

{
  "ok": true,
  "cluster_name": "test",
  "nodes": {
    "NLVBbJpJTZWefeI2kQt3Tg": {
      "name": "inventory_management",
      "transport_address": "inet[/127.0.0.1:9300]",
      "hostname": "devhost1",
      "version": "0.90.5",
      "http_address": "inet[/127.0.0.1:9200]"
    }
  }
}

...9200/_cluster/health?pretty=true

{
  "cluster_name" : "test",
  "status" : "green",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 0,
  "active_shards" : 0,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 0
}

Java 代码:

Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "test").put("node.name", "inventory_management").build();
Client client = new TransportClient(settings).addTransportAddress(new InetSocketTransportAddress("localhost", 9300));
IndexResponse response = client.prepareIndex("twitter", "tweet", "1").setSource(json).execute().actionGet();

异常(exception):

org.elasticsearch.transport.NodeDisconnectedException: [][inet[localhost/127.0.0.1:9300]][/cluster/nodes/info]

来自客户端的日志(Java API):

在 Java API 中尝试单播同样的错误。

discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: "localhost" # Tried with devhost1 127.0.0.1 as well and ["localhost"] too

这是服务器日志:

问题已按以下方式解决。确保您的客户端和服务器版本同步!

最佳答案

只是为了让可能遇到相同问题的其他人将此问题标记为已回答(答案实际上在问题的末尾)。

我遇到了同样的问题，结果证明是 Java 客户端使用的 JAR 版本与服务器运行的版本之间存在差异。您最好的选择是确保完全匹配，然后给出here 的说明。无需任何调整即可工作。

要检查的另一件事是您的 Java 客户端是否使用了正确的端口，而 不是 http 客户端使用的端口。正确的端口默认为 9300 而不是 9200，后者使用的是 9200。
