# 一.问题描述 #

最近在自学pyspark，想本地通过pycharm来编辑pyspark脚本，运行的时候，提示没有pyspark模块，于是通过pycharm安装了pyspark(最新版本)。

**而且这个安装到了远程服务器上，真的坑**

奈何我安装的是CDH 6.3.1版本，然后spark版本是 2.4.0-cdh6.3.1，然后最新版本是3.0.2的

新的pyspak程序，都未记录到 History Server服务上。

重新安装了pyspark 2.4.0版本，依旧未记录到 History Server服务上。

# 二.解决方案 #

首先想到的问题是卸载spark，然后重新安装

## 2.1 删除spark ##

更改配置后重新先停止然后删除spark

**界面删除了spark，依旧可以运行pyspark**
