我正在尝试读取一个简单的csv文件azuredatalakestoragev2和spark2.4在我的intellijide上的mac
下面的代码

package com.example

import org.apache.spark.SparkConf
import org.apache.spark.sql._

object Test extends App {

  val appName: String = "DataExtract"
  val master: String = "local[*]"
  val sparkConf: SparkConf = new SparkConf()
    .setAppName(appName)
    .setMaster(master)
    .set("spark.scheduler.mode", "FAIR")
    .set("spark.sql.session.timeZone", "UTC")
    .set("spark.sql.shuffle.partitions", "32")
    .set("fs.defaultFS", "abfs://development@xyz.dfs.core.windows.net/")
    .set("fs.azure.account.key.xyz.dfs.core.windows.net", "~~key~~")

  val spark: SparkSession = SparkSession
    .builder()
    .config(sparkConf)
    .getOrCreate()
  spark.time(run(spark))

def run(spark: SparkSession): Unit = {

  val df = spark.read.csv("abfs://development@xyz.dfs.core.windows.net/development/sales.csv")
  df.show(10)

}

}

它能够读取,并引发安全异常

根据我的研究,当您的jar与hadoop版本不兼容时,您将收到此错误消息。
