Hue的全局配置文件hue.ini（图文详解）

Hue版本：hue-3.9.0-cdh5.5.4

 需要编译才能使用（联网）


　说给大家的话：大家电脑的配置好的话，一定要安装cloudera manager。毕竟是一家人的。
同时，我也亲身经历过，会有部分组件版本出现问题安装起来要个大半天时间去排除，做好心里准备。废话不多说，因为我目前读研，自己笔记本电脑最大8G，只能玩手动来练手。
纯粹是为了给身边没高配且条件有限的学生党看的！ 但我已经在实验室机器群里搭建好cloudera manager 以及 ambari都有。

　　首先，大家一应要看清我的3个节点的集群机器情况！（不看清楚，自己去后悔吧）

进入 $HUE_HOME/desktop/conf/hue.ini
