本篇教程探讨了大数据技术 Hue的全局配置文件hue.ini，希望阅读本篇文章以后大家有所收获，帮助大家对大数据技术的理解更加深入。
<
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。
大数据领域两大最主流集群管理工具Ambari和Cloudera Manger

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
关于这里，给大家一个很好的技巧
大数据搭建各个子项目时配置文件技巧（适合CentOS和Ubuntu系统）
以下是我的配置文件（注意不是默认的）（作为大家参考） （这个配置文件，是根据大家的机器变动而走的）（动态的）
