进入mysql

mysql -uroot -p //默认没有密码

CREATE USER 'hive' IDENTIFIED BY 'mysql';

GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%' WITH GRANT OPTION;

mysql -uhive -pmysql//以hive用户进入mysql
create database hive;

wget http://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.11.tar.gz/from/http://mysql.he.net/ tar -xvzf mysql-connector-java-5.1.11.tar.gz
cp mysql-connector-java-5.1.11/*.jar $HIVE_HOME/lib
