hive元数据库配置

这个碰到过很多次了，记录一下

root用户不要设置密码

create database hive;

use mysql

create user 'hive' identified by 'hive';

update user set Password = password('hive') where User='hive';

grant all privileges on *.* to 'hive'@'%' identified by 'hive';

grant all privileges on *.* to hive@"localhost" identified by "hive";

grant all privileges on *.* to hive@"192.168.0.203" identified by "hive";

flush privileges;
