大数据可视化工具Hue安装使用

• Hue功能 及编译
  1）安装系统包

  yum install ant asciidoc cyrus-sasl-devel cyrus-sasl-gssapi gcc gcc-c++ krb5-devel 
  libtidy libxml2-devel libxslt-devel openldap-devel python-devel sqlite-devel 
  openssl-devel mysql-devel gmp-devel
  

  2）编译hue

  切换到hue目录下执行命令：make apps

  3）修改hue.ini文件

  secret_key=jFE93j;2[290-eiw.KEiwN2s3['d;/.q[eIW^y#e=+Iei*@Mn<qW5o
  
  
  # Webserver listens on this address and port
  
  http_host=bigdata.eclipse.com
  http_port=8888
  
  
  # Time zone name
  
  time_zone=Asia/Shanghai

• Hue与 HDFS、YARN 集成配置与测试 集成配置与测试
  1）hdfs-site.xml 文件配置

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

  2）core-site.xml 文件配置

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

  3） hue.ini 文件配置
