hive启动时报错

 
  问题： hive启动时报错 Access denied for user 'hive'@'master' (using password: YES) 
 

 
  环境： 
   hive1.2.2  
  hadoop2.6.1 
 

 
  步骤： 
 

 
  1  
   mysql安装配置和权限

 
  安装完成后 ，执行 
 

 
  update user set host='%' where host='localhost' 
 

 
  这个可以使外部本机访问虚拟机的mysql，然后直接在navicat修改mysql库的user表

  配置hive-site.xml

 
  hive-ite.xml中的配置很多，我们需要修改的是下面的这些，下面的description就能看出来配置的作用
