java - ElasticSearch 给出 ReceiveTimeoutTransportException

Question

您好，我正在尝试将我的 ElasticSearch 客户端连接到我的本地主机并尝试从那里获取索引。

import org.elasticsearch.action.get.GetResponse;
import org.elasticsearch.client.Client;
import org.elasticsearch.node.Node;
import org.elasticsearch.client.transport.*;
import org.elasticsearch.common.transport.*;
import java.io.IOException;
import static org.elasticsearch.node.NodeBuilder.nodeBuilder;
public class ESClient
{
    public static void search()throws IOException
    {
        Node node;
        node = nodeBuilder().clusterName("elasticsearch").node();
        Client client;
        client= new TransportClient()
                .addTransportAddress(new InetSocketTransportAddress("localhost", 9200));
        GetResponse response;
        response= client.prepareGet("twitter", "tweet", "1").execute() .actionGet();
        System.out.println(response.toString());

    }
    public static void main(String args[])throws IOException
    {
        search();

    }

}

我已经使用终端创建了索引。

curl -XPUT 'http://localhost:9200/twitter/' curl -XPUT 'http://localhost:9200/twitter/_mapping/tweet' -d ' {
"tweet" : { "properties" : {
"message" : {"type" : "string", "store" : true } }
} } '

当我执行它时，抛出以下错误，

NFO: [Blackheath] failed to get node info for [#transport#-1][BLRMCB-C02L56J4DR53.local][inet[localhost/127.0.0.1:9200]], disconnecting... org.elasticsearch.transport.ReceiveTimeoutTransportException: [][inet[localhost/127.0.0.1:9200]][cluster:monitor/nodes/info] request_id [0] timed out after [5002ms] at org.elasticsearch.transport.TransportService$TimeoutHandler.run(TransportService.java:366) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)

这是什么问题，谁能告诉我？

Answer 1

当我从使用 ElasticSearchAdapter 进行查询切换到使用 SparkStreamingAdapter 进行相同查询时，我遇到了这个错误。我不得不将端口更改为9300，然后就没有出现这个错误。

这个问题/答案帮助我解决了这个问题: Why can't I connect to ElasticSearch through Java API?
