Question

我安装了5.4.1版本，因为必须使用该版本。

我的服务器运行良好：

<div class="hero__description-right">
  <li class="description__item">
    <h2><span class="hashtag">#</span> Text</h2>
  </li>
  <li class="description__item test">
    <h2><span class="hashtag">#</span> Text</h2>
  </li>
  <li class="description__item">
    <h2><span class="hashtag">#</span> Text</h2>
  </li>
</div>

这是我的Java代码：

{
  "name" : "-0nx3wo",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "vxBcsrv9TXyUeLYFFVUkpQ",
  "version" : {
    "number" : "5.4.1",
    "build_hash" : "2cfe0df",
    "build_date" : "2017-05-29T16:05:51.443Z",
    "build_snapshot" : false,
    "lucene_version" : "6.5.1"
  },
  "tagline" : "You Know, for Search"
}

这是错误：

public class Connection {

    public static void main(String[] args) throws UnknownHostException {

        TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)
                .addTransportAddress(
                        new InetSocketTransportAddress(
                                InetAddress.getByName("localhost"), 9300));

        client.close();
    }

}

因此，看起来好像在调用no modules loaded loaded plugin [org.elasticsearch.index.reindex.ReindexPlugin] loaded plugin [org.elasticsearch.join.ParentJoinPlugin] loaded plugin [org.elasticsearch.percolator.PercolatorPlugin] loaded plugin [org.elasticsearch.script.mustache.MustachePlugin] loaded plugin [org.elasticsearch.transport.Netty4Plugin] Exception in thread "main" java.lang.IllegalArgumentException: NamedWriteable [org.elasticsearch.index.query.QueryBuilder][has_child] is already registered for [org.elasticsearch.search.SearchModule$$Lambda$268/1558103808], cannot register [org.elasticsearch.join.ParentJoinPlugin$$Lambda$356/1560702077] at org.elasticsearch.common.io.stream.NamedWriteableRegistry.<init>(NamedWriteableRegistry.java:91) at org.elasticsearch.client.transport.TransportClient.buildTemplate(TransportClient.java:150) at org.elasticsearch.client.transport.TransportClient.<init>(TransportClient.java:268) at org.elasticsearch.transport.client.PreBuiltTransportClient.<init>(PreBuiltTransportClient.java:128) at org.elasticsearch.transport.client.PreBuiltTransportClient.<init>(PreBuiltTransportClient.java:114) at org.elasticsearch.transport.client.PreBuiltTransportClient.<init>(PreBuiltTransportClient.java:104) at Connection.main(Connection.java:15)时出现了错误（由于行号addTransportAddress），但老实说我无法解决我的问题。我检查了类似这样的主题（ElasticSearch TransportClient version 5.6），但没有一个帮助

ElasticSearch TransportClient版本5.4.1
