之前安装了hive（地址：https://blog.csdn.net/qq_43437122/article/details/104989110），今天练习命令的时候出了问题，问题如下：

这个问题呢和创建表报错还是不太一样的，大部分是让设置mysql数据库里面hive数据库的编码为latin1，但是修改过后依然没有用，其实呢，这个问题产生原因是你的mysql-connector.x.x.x.jar的版本太旧了（我的是5.1.8的），所以你需要下载个高版本的jar文件。

建议下载5.1.34版本的就可以了，版本太新了的话会有警告。
删除掉旧的版本，把新版本放入lib目录下就行了，重新进入hive，如下图删除成功。
