Hue版本：我们使用Hue 3.11.0

Hue安装

• 下载地址：
  https://dl.dropboxusercontent.com/u/730827/hue/releases/3.11.0/hue-3.11.0.tgz
  并拷贝到安装目录，我的电脑安装目录是：/Users/****/apps
• 修改Hadoop的配置文件
  停止Hadoop的服务：

 $HADOOP_HOME/sbin/stop-all.sh

修改core-site.xml文件，添加如下内容：

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

修改hdfs-site.xml文件，添加如下内容：

  <property>
       <name>dfs.webhdfs.enabled</name>
       <value>true</value>
   </property>

再重新启动Hadoop的服务：

 $HADOOP_HOME/sbin/start-all.sh &

• 安装
  安装依赖，Hue需要很多依赖包，每个操作系统依赖各不相同，具体可以参照链接：https://github.com/cloudera/hue#development-prerequisites
  Mac的安装依赖如下：

brew install gmp
brew install mysql
brew install openssl
export LDFLAGS=-L/usr/local/opt/openssl/lib && export CPPFLAGS=-I/usr/local/opt/openssl/include

解压、进入解压目录、安装

tar zxvf hue-3.11.0.tgz
cd hue-3.11.0

• 修改配置文件

vim desktop/conf/hue.ini

参考官方链接：http://gethue.com/how-to-configure-hue-in-your-hadoop-cluster/
修改[desktop],[hadoop],[beeswax],[database]配置节相关内容如下：

desktop配置:

[desktop]

  # This is used for secure hashing in the session store.
  secret_key=

  # Execute this script to produce the Django secret key. This will be used when
  # 'secret_key' is not set.
  ## secret_key_script=

  ## send_dbug_messages=false

  # Enable or disable backtrace for server error

  # Webserver runs as this user
  server_user=hue
  server_group=hue

  # This should be the Hue admin and proxy user
  default_user=hue

  # This should be the hadoop cluster admin
  default_hdfs_superuser=hdfs

hadoop配置:

[hadoop]

  # Configuration for HDFS NameNode
  # ------------------------------------------------------------------------
  [[hdfs_clusters]]
    # HA support by using HttpFs

    [[[default]]]
      # Enter the filesystem uri

      # NameNode logical name.
      ## logical_name=

      # Use WebHdfs/HttpFs as the communication mechanism.

      # Change this if your HDFS cluster is Kerberos-secured
      ## security_enabled=false

      # Whether to submit jobs to this cluster
      submit_to=True

      # Resource Manager logical name (required for HA)
      ## logical_name=

      resourcemanager_api_url=http://localhost:8088

      # URL of the ProxyServer API
      ## proxy_api_url=http://localhost:8088

      # URL of the HistoryServer API
      history_server_api_url=http://localhost:19888

beeswax配置：

[beeswax]

  # Host where HiveServer2 is running.
  # If Kerberos security is enabled, use fully-qualified domain name (FQDN).
  hive_server_host=localhost

  # Port where HiveServer2 Thrift server runs on.
  hive_server_port=10000

  # Hive configuration directory, where hive-site.xml is located
  hive_conf_dir=$HIVE_HOME/conf

database配置：

[[database]]
    # Database engine is typically one of:
    # postgresql_psycopg2, mysql, sqlite3 or oracle.
    #
    # Note that for sqlite3, 'name', below is a path to the filename. For other backends, it is the database name
    # Note for Oracle, options={"threaded":true} must be set in order to avoid crashes.
    # Note for Oracle, you can use the Oracle Service Name by setting "host=" and "port=" and then "name=<host>:<port>/<service_name>".
    # Note for MariaDB use the 'mysql' engine.
    engine=mysql
    host=localhost
    port=3306
    user=root
    password=hive123456
    # Execute this script to produce the database password. This will be used when 'password' is not set.
    ## password_script=/path/script
    name=hue

• 构建Hue数据库
  连接本地mysql数据库服务器：

  
  
  hue-1.png

依次执行如下命令：

create database hue;
grant all privileges on hue.* to root@'%' identified by'hive123456';
flush privileges;

再切换到hue的安装目录，执行：

build/env/bin/hue syncdb

hue-2.png

最后终于可以启动Hue的服务了：

build/env/bin/supervisor  

• 打开Hue
  在浏览器中输入地址：http://127.0.0.1:8888/

后面的文章将使用Hue查询Hive和HBase以及Spark等。
