大数据学习——hive本地模式安装遇到的问题

安装hive的本地模式需要提前安装并配置好mysql，
我安装MySQL参照的文章:https://www.runoob.com/mysql/mysql-install.html
更新yum源后若出现了问题可以参照我的另外一篇文章：
https://blog.csdn.net/qq_41934760/article/details/105788395

配置MySQL时，需要创建hive用户并设置密码，命令是

create user hive IDENTIFIED by 'hive'

The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

解决办法：
终端输入

sudo vim /etc/my.cnf

skip grant tables

flush privileges

hive配置文件的修改

复制hive安装目录下的/conf/hive-default.xml.template文件为hive-site.xml,
进入conf目录打开终端并输入命令:

cp hive-default.xml.template hive-site.xml

echo " " > hive-site.xml

sudo vi hive-site.xml
