运行配置单元命令后,无法创建数据库
遵循apache网站上的官方“入门”指南

我刚刚在hive:hive-site.xml和创建/user/hive/warehouse的安装步骤中实现了:
“user”很容易与“usr”混淆,根本没有任何警告。所以请记住:
在hadoop fs下,要创建的是/user/hive/warehouse,它指向metadata\u db文件夹(而不是/usr/hive/warehouse)

检查特定用户是否有创建的权限 /opt/hive/bin/metastore_db 如果没有,则添加权限

sudo chmod -R 777 /opt/hive/bin/metastore_db

希望这有帮助

用法:chown-rhduser:hduser */hive/(*或您正在使用的任何用户名/用户组)授予所有者(因此具有完全权限…..包括写入/创建)
(我不知道是否有一个名为hive:hive,我创建了此配置单元,但将所有权授予此用户创建的配置单元将不起作用..)
基本上,安装说明假设您(hadoop和继承您权利的hive)拥有足够的权限。
(注意:这相当于在windows中以管理模式运行命令提示符,即使您已经是管理员)。linux在很多方面都很灵活,因此会造成一些混乱。
