当我尝试将Elasticsearch与Spark连接时出现此错误：

代码如下：
SparkConf conf = new SparkConf()
.setAppName("ES-Spark")
.("local[*]")
.set("es.nodes", "cluster-xxxx.xx.xx.xx")
.set("es.port", "50467")
.set("es.resource", "recommendations_2/recommendation")
.set("es.resource.read", "products-20190912/product")
.set("es.resource.write", "recommendations_2/recommendation")
;
JavaSparkContext ctx = new JavaSparkContext(conf);
JavaStreamingContext jsc = new JavaStreamingContext(ctx, new Duration(10000));
JavaInputDStream<ConsumerRecord<String, String>> kafkaStream = Utils.getKafkaStream(jsc);
JavaDStream<String> allInfo = kafkaStream.map(f -> f.value());
JavaEsSparkStreaming.saveToEs(allInfo, "recommendations_2/recommendation");
jsc.start();
jsc.awaitTermination();
似乎它到达了群集，但无法重新连接...
使用的依赖项是：
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch-spark-20_2.10</artifactId>
<version>5.6.2</version>
</dependency>
当我尝试通过传输客户端进行连接时，一切都很好，我能够做到。
我已经检查了 elasticsearch.yml 文件，并且 http.port 属性已正确设置为正确的端口。
