先来看下hue的架构图：

（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？  
  
centos系统，执行命令：  
yum install -y asciidoc cyrus-sasl-devel cyrus-sasl-gssapi gcc gcc-c++ krb5-devel libtidy libxml2-devel libxslt-devel make mysql mysql-devel openldap-devel python-devel sqlite-devel openssl-devel gmp-devel  
  
  
1，hue的依赖（centos系统）

ant
    asciidoc
    cyrus-sasl-devel
    cyrus-sasl-gssapi
    gcc
    gcc-c++
    krb5-devel
    libtidy (for unit tests only)
    libxml2-devel
    libxslt-devel
    make
    mvn (from maven package or maven3 tarball)
    mysql
    mysql-devel
    openldap-devel
    python-devel
    sqlite-devel
    openssl-devel (for version 7+)

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：

user="search"
    
    # java
    export JAVA_HOME="/usr/local/jdk"
    export CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
    export PATH=$PATH:$JAVA_HOME/bin
    
    # ant 
    export ANT_HOME=/usr/local/ant
    export CLASSPATH=$CLASSPATH:$ANT_HOME/lib
    export PATH=$PATH:$ANT_HOME/bin
    
    # maven 
    export MAVEN_HOME="/usr/local/maven"
    export CLASSPATH=$CLASSPATH:$MAVEN_HOME/lib
    export PATH=$PATH:$MAVEN_HOME/bin
    
    
    ##Hadoop2.2的变量设置
    export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin
    export HADOOP_HOME=/home/search/hadoop
    export HADOOP_MAPRED_HOME=$HADOOP_HOME
    export HADOOP_COMMON_HOME=$HADOOP_HOME
    export HADOOP_HDFS_HOME=$HADOOP_HOME
    export YARN_HOME=$HADOOP_HOME
    export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
    export YARN_CONF_DIR=$HADOOP_HOME/etc/hadoop
    export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin
    export CLASSPATH=.:$CLASSPATH:$HADOOP_COMMON_HOME:$HADOOP_COMMON_HOMEi/lib:$HADOOP_MAPRED_HOME:$HADOOP_HDFS_HOME:$HADOOP_HDFS_HOME
    
    
    # Hive 
    
    export HIVE_HOME=/home/search/hive  
    export HIVE_CONF_DIR=/home/search/hive/conf  
    export CLASSPATH=$CLASSPATH:$HIVE_HOME/lib  
    export PATH=$PATH:$HIVE_HOME/bin:$HIVE_HOME/conf 
    
    
    export OOZIE_HOME="/home/search/oozie-4.1.0"
    export PATH=$PATH:$OOZIE_HOME/sbin:$OOZIE_HOME/bin

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：\[url\]https://github.com/cloudera/hue/releases\[/url\]  
  
hue的github地址：\[url\]https://github.com/cloudera/hue\[/url\]  
  
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。

6，启动hue，执行命令：build/env/bin/supervisor

[search@h1 hue]$ build/env/bin/supervisor 
    [INFO] Not running as root, skipping privilege drop
    starting server with options {'ssl_certificate': None, 'workdir': None, 'server_name': 'localhost', 'host': '0.0.0.0', 'daemonize': False, 'threads': 10, 'pidfile': None, 'ssl_private_key': None, 'server_group': 'search', 'ssl_cipher_list': 'DEFAULT:!aNULL:!eNULL:!LOW:!EXPORT:!SSLv2', 'port': 8000, 'server_user': 'search'}

然后我们就可以访问安装机ip+8000端口来查看了：

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  
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

<property>
      <name>hive.metastore.warehouse.dir</name>
      <value>/user/hive/warehouse</value>
      <description>location of default database for the warehouse</description>
    </property>
    <property>
      <name>hive.server2.thrift.port</name>
      <value>10000</value>
      <description>Port number of HiveServer2 Thrift interface.
      Can be overridden by setting $HIVE_SERVER2_THRIFT_PORT</description>
    </property>
    
    <property>
      <name>hive.server2.thrift.bind.host</name>
      <value>h1</value>
      <description>Bind host on which to run the HiveServer2 Thrift interface.
      Can be overridden by setting $HIVE_SERVER2_THRIFT_BIND_HOST</description>
    </property>
    
    <property>
      <name>hive.server2.authentication</name>
      <value>NOSASL</value>
      <description>
        Client authentication types.
           NONE: no authentication check
           LDAP: LDAP/AD based authentication
           KERBEROS: Kerberos/GSSAPI authentication
           CUSTOM: Custom authentication provider
                   (Use with property hive.server2.custom.authentication.class)
           PAM: Pluggable authentication module.
      </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。

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：

<property>
           <name>hadoop.proxyuser.hue.hosts</name>
          <value>*</value>
      </property>
    
    
        <property>
          <name>hadoop.proxyuser.hue.groups</name>
          <value>*</value>
         </property>

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！
