Error executing Jupyter command 'WordCount.py': [Errno 2] No such file or directory

因为课程要求，最近疯狂搭建hadoop集群和spark环境，遇到一些问题，特此记录。

问题描述：
搭建了pycharm+pyspark环境之后，想测试下上传测试文件到HDFS目录，输入命令HADOOP_CONF_DIR=/root/app/hadoop/etc/hadoop spark-submit --driver-memory 512m --executor-cores 2 --master yarn --deploy-mode client WordCount.py
后报错，报错信息如下：

[root@hadoop1 ipynotebook]# HADOOP_CONF_DIR=/root/app/hadoop/etc/hadoop spark-submit --driver-memory 512m --executor-cores 2 --master yarn --deploy-mode client WordCount.py
Error executing Jupyter command '/root/pythonwork/ipynotebook/WordCount.py': [Errno 2] No such file or directory

问题分析：
因为在此之前我测试了jupyter所以把环境变量改成了jupyter

解决方法：
重新编辑环境变量

成功
