1下载并安装MySQL并启动服务(我的MySQL安装在宿主机Windows下)
2在MySQL中建立数据库用于存放Hive元数据,并为为数据库建立账号,并赋予需要的权限
3下载并解压Hive
4为Hive配置环境变量
5配置hive-config.sh文件
6配置hive-site.xml文件,并配置MySQL连接信息
7把mysql-connector-java-x.x.x.jar 复制到Hive的lib目录下
8启动Hive
9验证Hive是否启动成功
格式:grant all privileges on 数据库.* to 用户名@登录主机 identified by "密码"
给远程权限
grant all privileges on *.* to hive@'%' identified by "hive" ;
给本地权限
grant all privileges on *.* to hive@localhost identified by "hive";
验证hive用户权限:
bin/mysql -u hive
先复制默认的,然后再修改
cp /home/hadoop/hive/conf/hive-default.xml.template /home/hadoop/hive/conf/hive-site.xml
然后修改下列属性
