Hive安装

hive-1.2.2下载地址
下载并解压hive源程序

sudo tar -zxvf ~/下载/apache-hive-1.2.2-bin.tar.gz -C /usr/local   # 解压到/usr/local中
cd /usr/local/
sudo mv apache-hive-1.2.2-bin hive       # 将文件夹名改为hive
sudo chown -R mashu:mashu hive            # 修改文件权限

为了方便使用，我们把hive命令加入到环境变量中去，编辑~/.bashrc文件vim ~/.bashrc，在最前面一行添加(详见图):

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

保存退出后，运行source ~/.bashrc使配置立即生效。

将/usr/local/hive/conf下的hive-default.xml.template重命名为hive-default.xml；新建一个文件touch hive-site.xml，并在hive-site.xml中粘贴如下配置信息：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
