我究竟做错了什么？为了在Docker容器内使用配置单元,我还需要做什么？
另外,我看到mysql正在运行
root@7bfa781e1a2c:/opt/hive/conf# ps aux | grep mysql
mysql 1931 0.0 0.0 4624 1768 ? S 20:19 0:00 /bin/sh /usr/bin/mysqld_safe
mysql 2282 0.2 8.7 1416908 179700 ?

root@7bfa781e1a2c:/opt/hive/conf#
最佳答案
有几个问题需要解决：
> mysql安装随附的默认root用户使用auth_socket作为身份验证插件.这意味着它没有密码.尝试使用mysql -uroot登录,它仍然会登录.

>因此,在mysql中进行任何更改之前,配置单元服务会引发以下错误：
由以下原因引起：java.sql.SQLException：用户’root’@’localhost’的访问被拒绝
>我们需要设置root @ localhost以使用mysql_native_password身份验证,并设置@rajesh提到的密码：
mysql> alter user root@localhost identified with mysql_native_password by 'password';

Bye
>仍然配置单元为我抛出错误,因为未更新加载的mysql模式.所以不得不做Hive 2.1.1 MetaException(message:Version information not found in metastore. )中提到的一些步骤
cd $HIVE_HOME/scripts/metastore/upgrade/mysql/
mysql -uroot -ppassword
mysql> use metastore;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> source hive-schema-2.3.0.mysql.sql;
>现在,配置单元开始正常.
