7.在hdfs上创建目录

cd /usr/hadoop/bin
hdfs dfs -mkdir -p /tmp
hdfs dfs -mkdir -p /user/hive/warehouse
hdfs dfs -chmod g+w /tmp
hdfs dfs -chmod g+w /user/hive/warehouse

8.在mysql中创建数据库

CREATE DATABASE hive;
GRANT ALL PRIVILEGES ON *.* TO user@% IDENTIFIED BY 123456 WITH GRANT OPTION;
ALTER DATABASE hive CHARACTER SET latin1;

9.手动上传mysql的jdbc库到hive/lib

mysql-connector-java-5.1.38-bin.jar

10.启动hive(也可以使用 ./hive)

cd /usr/apache-hive-2.0.0-bin

启动metastore服务

bin/hive --service metastore &

启动hiveserver服务

bin/hive --service hiveserver2 &

启动hive客户端

bin/hive shell

11.查看mysql元数据是否已经初始化

好了，至此hive已经安装成功了。
