                        <manifest>
                            <mainClass>numCount.main</mainClass>

    </build>
</project>

com.test.list.numCount

package com.test.list

import org.apache.spark.{SparkConf, SparkContext}

object numCount {
  def main(args: Array[String]): Unit = {

    //TODO 准备环境
    val sparkConf = new SparkConf().setMaster("local[*]").setAppName("numCount")
    val sc = new SparkContext(sparkConf)

    //TODO 算子 - map
    val list = sc.makeRDD(List(1,2,3,4,5,6,7,2,8),2)
    val value = list.sortBy(num=>num, true, 4)

    value.collect().foreach(println)


    //TODO 关闭环境
    sc.stop()

  }
  def mapFunction(num:Int):Int = {
    num * 2
  }
}

2.打包项目为jar上传至虚拟机目录

3.提交运行

bin/spark-submit # 提交入口
–class com.test.list.numCount #jar代码中java的子包名
–master local[2] #设置核数
examples/jars/spark-numCount-test.jar #jar位置

 bin/spark-submit --class com.test.list.numCount --master local[2] examples/jars/spark-numCount-test.jar

4.运行截图
