一、安装

下载后解压，配置很简单，底层是MR程序，所以只需要设置一下环境变量就可以使用了。

# hadoop的安装目录和hive的conf目录
# Set HADOOP_HOME to point to a specific hadoop install directory
HADOOP_HOME=/home/hadoop/cdh/hadoop-2.5.0-cdh5.3.6

# Hive Configuration Directory can be controlled by:
export HIVE_CONF_DIR=/home/hadoop/cdh/hive-0.13.1-cdh5.3.6/conf

进入hive进行测试

bin/hive
show databases;

</property>

2、接入hue需要的配置

<property>
