【工具】大数据在线分析利器：Hue

Hue百科：

Hue 是一种基于Apche hadoop基础平台的在线开源数据分析接口，参见 gethue.com

Hue的主要功能:

• 提供SQL 接口：Hive, Impala, MySql, PostGres, Sqlite and Oracle ；
• 提供Solr动态查询面板；
• 提供Spark 编辑器；
• 提供浏览界面：YARN, HDFS, Hive table Metastore, HBase, ZooKeeper；
• 提供 Sqoop2编辑器、 Oozie 流编辑器和控制面板；
• 提供Hadoop数据加载向导；

除此，它还提供一个创建hadoop应用的SDK，更多开发文档在 gethue.com

如何开始？

首先建立服务器运行环境：

$ git clone https://github.com/cloudera/hue.git
$ cd hue
$ make apps
$ build/env/bin/hue runserver

现在Hue已经运行在本地 http://localhost:8000 !

开发配置文件是 desktop/conf/pseudo-distributed.ini.

接下来启动生产环境：

$ build/env/bin/supervisor

启动测试:

安装最小集群 (仅一次):

$ ./tools/jenkins/jenkins.sh slow

开始全部测试:

$ build/env/bin/hue test all

或者逐项测试，如:

$ build/env/bin/hue test specific impala
$ build/env/bin/hue test specific impala.tests:TestMockedImpala
$ build/env/bin/hue test specific impala.tests:TestMockedImpala.test_basic_flow

开发环境需求

你的系统里需要安装和运行如下的程序包和工具：

Ubuntu:

• ant
• gcc
• g++
• libkrb5-dev
• libmysqlclient-dev
• libssl-dev
• libsasl2-dev
• libsasl2-modules-gssapi-mit
• libsqlite3-dev
• libtidy-0.99-0 (for unit tests only)
• libxml2-dev
• libxslt-dev
• make
• mvn (from maven package or maven3 tarball)
• openldap-dev / libldap2-dev
• python-dev
• python-setuptools
• libgmp3-dev

CentOS/RHEL:

• 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+)
• gmp-devel

MacOS:

• Xcode command line tools
• Oracle’s JDK 1.7+
• maven (Homebrew)
• mysql (Homebrew)
• gmp (Homebrew)
• openssl (Homebrew)
• Required for Mac OS X 10.11+ (El Capitan), after brew install openssl, run: export LDFLAGS=-L/usr/local/opt/openssl/lib && export CPPFLAGS=-I/usr/local/opt/openssl/include

文件列表

Hue的框架文件在 desktop/core里 ，其中含有web组件；destop/libs是Hadoop服务API接口；可以运行的APP在apps/里；第三方独立应用可以放置在ext-py/目录下。

一个应用的典型目录结构如下：

  src/
    for Python/Django code
      models.py
      urls.py
      views.py
      forms.py
      settings.py

  conf/
    for configuration (``.ini``) files to be installed

  static/
    for static HTML/js resources and help doc

  templates/
    for data to be put through a template engine

  locales/
    for localizations in multiple languages

For the URLs within your application, you should make your own urls.py which will be automatically rooted at /yourappname/in the global namespace. See apps/about/src/about/urls.py for an example.

你可以通过ulrs.py声明你自己应用的URL地址，这些URL地址通过全局命名里的/yourappname/自动被root，更多例子请参考apps/about/src/about/urls.py

代码栈

Hue 的代码栈如下:

• Python 2.6.5 – 2.7
• Django 1.6 (https://docs.djangoproject.com/en/1.6/)
• Knockout.js (http://knockoutjs.com/)
• jQuery (http://jquery.com/)
• Bootstrap (http://getbootstrap.com/)
