Apache spark Spark至AWS ElasticSearch服务

我正在本地机器上运行spark。我已在AWS ElasticSearch服务中启动并运行ElasticSearch。我试图遵循此处指定的文档：

我使用的Elasticsearch spark版本是

        <dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch-spark-20_2.10</artifactId>
            <version>7.5.0</version>
        </dependency>

我试着去调试到底是什么问题。这是我在第745行的package

org.elasticsearch.hadoop.rest.RestClient.java中找到的

Map<String, Object> result = get("", null);

Map result=get（“，null）；

不确定他们为什么要将get方法中的URI设置为空字符串。任何帮助都将不胜感激。
我也有同样的问题。你的帖子帮我解决了我的问题。我的一个区别是“es.nodes”字段；在端点前面添加“https://”对我来说很有效。我也有同样的问题。你的帖子帮我解决了我的问题。我的一个区别是“es.nodes”字段；在端点前面添加“https://”对我来说很有效。
import static org.elasticsearch.spark.streaming.api.java.JavaEsSparkStreaming.saveToEs;

public class ElasticSearchManager {

    public static void sendToEs(JavaDStream<Map<String, Object>> javaDStream) {
        ZonedDateTime dateTime = LocalDateTime.now().atZone(ZoneId.systemDefault());
        saveToEs(javaDStream,
                dateTime.format(DateTimeFormatter.ofPattern("YYYY-MM-dd")));

    }
}
