spark运行报错Please install psutil to have better support with spilling

记录一下错误，在windows上面运行spark报错

 words = sc.parallelize(['scala','java','hadoop','spark','scala','hadoop','spark','scala'])

words.distinct().count()

最然能够运行出结果，但是会报错 

        Please install psutil to have better support with spilling

解决办法：

        直接在cmd上面pip install psutil就行
