代码如下

```python


# coding:utf8
from pyspark import SparkConf, SparkContext
import os

if __name__ == '__main__':
    os.environ['SPARK_HOME'] = "C:\\Users\\tongmig\\AppData\\Local\\Programs\\Python\\Python39\\Lib\\site-packages" \
                               "\\pyspark "
    conf = SparkConf().setAppName("WordCountHelloWorld")
    # 通过SparkConf对象构建SparkContext对象
    sc = SparkContext(conf=conf)

    # 需求 : wordcount单词计数, 读取HDFS上的words.txt文件, 对其内部的单词统计出现 的数量
    # 读取文件
    file_rdd = sc.textFile("C:\\Users\\tongmig\\Desktop\\word_count.txt")

    # 将单词进行切割, 得到一个存储全部单词的集合对象
    words_rdd = file_rdd.flatMap(lambda line: line.split(" "))

    # 将单词转换为元组对象, key是单词, value是数字1
    words_with_one_rdd = words_rdd.map(lambda x: (x, 1))

    # 将元组的value 按照key来分组, 对所有的value执行聚合操作(相加)
    result_rdd = words_with_one_rdd.reduceByKey(lambda a, b: a + b)

    # 通过collect方法收集RDD的数据打印输出结果
    print(result_rdd.collect())

检查一下这个路径是否正确： file_rdd = sc.textFile("C:\Users\tongmig\Desktop\word_count.txt")
