sudo mv apache-hive-1.2.2-bin hive

文件夹权限修改

sudo chown -R hadoop:hadoop ./hive

配置环境变量

sudo vim ~/.bashrc

export HIVE_HOME=/usr/local/hive

export PATH=$PATH:$HIVE_HOME/bin

export HIVE_CONF_DIR=$HIVE_HOME/conf

配置生效

source ~/.bashrc

在master节点上安装mysql

sudo apt-get install mysql-server

启动mysql

service mysqld start

chkconfig mysqld on

chkconfig mysql on 是设置开机启动

将mysql 中的connector jar包拷贝到hive中lib文件夹下

cp mysql-connector-java-5.1.46 /usr/local/hive/lib/

在mysql上创建hive元数据库，创建hive账号，并进行授权

进入mysql

mysql -uroot -p

创建hive数据库

create database if not exists hive;

赋值权限

grant all privileges on hive.* to 'hive'@'%' identified by 'hive';
grant all privileges on hive.* to 'hive'@'localhost' identified by 'hive';
grant all privileges on hive.* to 'hive'@'Master' identified by 'hive';

刷新权限

flush privileges;

进入hive数据库

use hive;
