hive单用户多点模式配置

简介

单用户多点模式也称远程服务模式，用户非java客户端访问元数据库，在服务端启动MetaStoreServer，客户端利用Thrift协议通过MetaStoreServer访问元数据库。

mysql安装以及配置

安装mysql

apt默认安装，占据3306端口

安装机器 : dev01

sudo apt-get install mysql-server

sudo apt-get install mysql-client

配置hive用户

1. 登陆mysql
   
   mysql -u root -p xxxxxx

2. 创建hive用户

   create user 'hive'@'%' identified by 'hive';

3. 给hive用户权限

   grant all privileges on *.* to 'hive'@'%' with grant option;

   flush privileges;

服务端配置

修改 $HIVE_HOME/conf/hive-site.xml
