Question

我试图在Windows上使用python运行一个简单的mapreduce字数计算程序，但出现以下错误：

下面是我使用的命令：

yarn jar C:\hadoop-3.2.2\share\hadoop\tools\lib\hadoop-streaming-3.2.2.jar -input /input -output /output2 -mapper "python D:\mapper.py" -reducer "python D:\reducer.py"

我使用了Hadoop 3.2.2，python脚本来自this site。我试着用谷歌搜索，但找不到解决办法。希望有人能告诉我如何解决这个问题或任何相关的职位
