先来看下hue的架构图：
2，散仙的在安装hue前，centos上已经安装好了，jdk，maven，ant，hadoop，hive，oozie等，环境变量如下：
Java代码
3,本文散仙主要是采用tar包的方式安装hue，除了tar包的方式，hue还能采用cm安装，当然这就与cdh的系统依赖比较大了。
hue最新的版本是3.8.1，散仙这里用的3.7.0的版本
下载地址： https://github.com/cloudera/hue/releases
hue的github地址： https://github.com/cloudera/hue
4，下载完后，解压tar包，并进入hue的根目录执行命令
make apps编译
5，编译成功后，需要配置/home/search/hue/desktop/conf/pseudo-distributed.ini文件，里面包含了hdfs，yarn，mapreduce，hive，oozie，pig，spark，solr等的ip地址和端口号配置，可根据自己的情况设置，如果没有安装某个应用，那就无须配置，只不过这个应用在web上不能使用而已，并不会影响其他框架的使用。
一个例子如下：
Java代码
6，启动hue，执行命令：build/env/bin/supervisor
Java代码
然后我们就可以访问安装机ip+8000端口来查看了：
工具箱界面：
hive的界面：
在配置hive（散仙这里是0.13的版本）的时候，需要注意以下几个方面：
hive的metastrore的服务和hiveserver2服务都需要启动
执行下面命令
除此之外，还需要关闭的hive的SAL认证，否则，使用hue访问会出现问题。
注意下面三项的配置
Java代码
除了上面的配置外，还需要把hive.server2.long.polling.timeout的参数值，默认是5000L给改成5000,否则使用beenline连接时候，会出错，这是hive的一个bug。
pig的界面：
solr的界面如下：
最后需要注意一点，hue也需要在hadoop的core-site.xml里面配置相应的代理用户，示例如下：
Java代码
ok至此，我们的hue已经能完美工作了，我们可以根据自己的需要，定制相应的app插件，非常灵活！
（1）Hue是什么？
Hue是一个可快速开发和调试Hadoop生态系统各种应用的一个基于浏览器的图形化用户接口。
（2）Hue能干什么？
1，访问HDFS和文件浏览
2，通过web调试和开发hive以及数据结果展示
3，查询solr和结果展示，报表生成
4，通过web调试和开发impala交互式SQL Query
5，spark调试和开发
6，Pig开发和调试
7，oozie任务的开发，监控，和工作流协调调度
8，Hbase数据查询和修改，数据展示
9，Hive的元数据（metastore）查询
10，MapReduce任务进度查看，日志追踪
11，创建和提交MapReduce，Streaming，Java job任务
12，Sqoop2的开发和调试
13，Zookeeper的浏览和编辑
14，数据库（MySQL，PostGres，SQlite，Oracle）的查询和展示
（3）Hue怎么用或者什么时候应该用？
如果你们公司用的是CDH的hadoop，那么很幸运，Hue也是出自CDH公司，自家的东西用起来当然很爽。
如果你们公司用的是Apache Hadoop或者是HDP的hadoop，那么也没事，Hue是开源的，而且支持任何版本的hadoop。
关于什么时候用，这纯属一个锦上添花的功能，你完全可以不用hue，因为各种开源项目都有自己的使用方式和开发接口，hue只不过是统一了各个项目的开发方式在一个接口里而已，这样比较方便而已，不用你一会准备使用hive，就开一个hive的cli终端，一会用pig，你就得开一个pig的grunt，或者你又想查Hbase，又得需要开一个Hbase的shell终端。如果你们使用hadoop生态系统的组件很多的情况下，使用hue还是比较方便的，另外一个好处就是hue提供了一个web的界面来开发和调试任务，不用我们再频繁登陆Linux来操作了。
你可以在任何时候，只要能上网，就可以通过hue来开发和调试数据，不用再装Linux的客户端来远程登陆操作了，这也是B/S架构的好处。
（4）如何下载，安装和编译Hue？

hive的界面：
在配置hive（散仙这里是0.13的版本）的时候，需要注意以下几个方面：
hive的metastrore的服务和hiveserver2服务都需要启动
执行下面命令
[Java]

复制代码

bin/hive --service metastore
bin/hiveserver2

除此之外，还需要关闭的hive的SAL认证，否则，使用hue访问会出现问题。
注意下面三项的配置

</description>
</property>

除了上面的配置外，还需要把hive.server2.long.polling.timeout的参数值，默认是5000L给改成5000,否则使用beenline连接时候，会出错，这是hive的一个bug。
pig的界面：
solr的界面如下：
最后需要注意一点，hue也需要在hadoop的core-site.xml里面配置相应的代理用户，示例如下：

ok至此，我们的hue已经能完美工作了，我们可以根据自己的需要，定制相应的app插件，非常灵活！
