配置环境变量

打开配置文件并敲如下命令：vi ~/.bashrc

JAVA_HOME=/usr/java/default
PATH=$PATH:$JAVA_HOME/bin

export JAVA_HOME PATH

运行命令使其生效

source ~/.bashrc

验证是否生效

[root@VM_0_16_centos java]# echo $JAVA_HOME
/usr/java/default
[root@VM_0_16_centos java]# echo $PATH
/usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/hive/bin:/usr/java/default/bin:/usr/java/default/bin

安装Hadoop

安装HIVE

下载 http://mirror.bit.edu.cn/apache/hive/

将hive解压到/usr/local下：

tar -zxvf apache-hive-3.1.2-bin.tar.gz -C /usr/local/

将文件重命名为 hive 文件：

mv apache-hive-2.1.1-bin hive

修改环境变量 /etc/profile

#hive
export HIVE_HOME=/usr/local/hive
export PATH=$PATH:$HIVE_HOME/bin

执行 source /etc.profile

执行 hive --version
