Spark完成wordCount

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

object WordCount {

  def main(args: Array[String]): Unit = {
    System.setProperty("hadoop.home.dir", "D:/winutils/")

    // 创建Spark配置，运行环境
    val sparkConf = new SparkConf()
    sparkConf.setAppName("WordCount")
    sparkConf.setMaster("local")
    // 创建Spark上下文对象
    val sparkContext = new SparkContext(sparkConf)
    // 从文件逐行读取到rdd
    val rdd = sparkContext.textFile("input/WordCountInput")
    // 将每一行内容分解为一个一个的单词
    val words = rdd.flatMap(line => line.split(","))
    // 转换数据结果并进行统计
    val count  = words.map(word => (word, 1)).reduceByKey(_+_)

    count.foreach(println(_))
  }
