初始化报该错CDH 初始化数据库 报错ERROR Exception when creating/dropping database with user ‘root’ and jdbc url ‘jdbc:mysql://localhost/?useUnicode=true&characterEncoding=UTF-8’，原因是没有该用户，无法创建。
初始化命令格式：
解决方法：进到mysql数据库里添加创建用户，格式如下
grant all privileges on . to ‘root’@‘localhost’ identified by ‘123456’ with grant option;
grant all privileges on . to ‘root’@‘hadoop1’ identified by ‘123456’ with grant option;
grant all privileges on . to ‘root’@‘127.0.0.1’ identified by ‘123456’ with grant option;
grant all privileges on . to ‘root’@’%’ identified by ‘123456’ with grant option;
grant all privileges on . to ‘scm’@‘localhost’ identified by ‘scm’ with grant option;
grant all privileges on . to ‘scm’@‘hadoop1’ identified by ‘scm’ with grant option;
grant all privileges on . to ‘scm’@‘127.0.0.1’ identified by ‘scm’ with grant option;
grant all privileges on . to ‘scm’@’%’ identified by ‘scm’ with grant option;
PS。如果数据库里有cm和scm表，需要先删除在重新初始化。
