將 JSON 數據寫入 MongoDB 本地的 Spark 作業錯誤

Question

我正在嘗試一個簡單的程序來讀取 JSON 文件並寫入 MongoDB 本地實例，我安裝了 Mongo DB

在 Spark 中寫了這個程序

import com.mongodb.spark.MongoSpark
import org.apache.spark.sql.{DataFrame, SparkSession}

    object Main extends App {

        val sparkSession = SparkSession.builder().appName("SparkMongo")
          .master("local[*]")
          .config("spark.mongodb.input.uri", "mongodb://localhost:27017/product.styles")
          .config("spark.mongodb.output.uri", "mongodb://localhost:27017/product.styles")
          .getOrCreate()

        var data : DataFrame = sparkSession.read.option("multiline", "true").json("/home/sandeep/style.json")
        MongoSpark.save(data)
    }

但是當我使用 Spark-Submit 運行時出現以下錯誤

不知道，我在哪里做錯了什么

您不需要為 mongodb 服務器指定端口嗎？
