簡介

單使用者多點模式也稱遠端服務模式，使用者非java客戶端訪問元資料庫，在服務端啟動MetaStoreServer，客戶端利用Thrift協議通過MetaStoreServer訪問元資料庫。

mysql安裝以及配置

安裝mysql

apt預設安裝，佔據3306埠

安裝機器 : dev01

sudo apt-get install mysql-server

sudo apt-get install mysql-client

配置hive使用者

1. 登陸mysql
   mysql -u root -p xxxxxx

2. 建立hive使用者

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

3. 給hive使用者許可權

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

   flush privileges;

服務端配置

修改 $HIVE_HOME/conf/hive-site.xml
