Hue是一个开源的Apache Hadoop UI系统,由Cloudera Desktop演化而来,最后Cloudera公司将其贡献给Apache基金会的Hadoop社区,它是基于Python Web框架Django实现的。通过使用Hue我们可以在浏览器端的Web控制台上与Hadoop集群进行交互来分析处理数据,例如操作HDFS上的数据,运行MapReduce Job,执行Hive的SQL语句,浏览HBase数据库等等
Hue在数据库方面,默认使用的是SQLite数据库来管理自身的数据,包括用户认证和授权,另外,可以自定义为MySQL数据库、Postgresql数据库、以及Oracle数据库。其自身的功能包含有:
对HDFS的访问,通过浏览器来查阅HDFS的数据。
Hive编辑器:可以编写HQL和运行HQL脚本,以及查看运行结果等相关Hive功能。
提供Solr搜索应用,并对应相应的可视化数据视图以及DashBoard。
提供Impala的应用进行数据交互查询。
最新的版本集成了Spark编辑器和DashBoard
支持Pig编辑器,并能够运行编写的脚本任务。
Oozie调度器,可以通过DashBoard来提交和监控Workflow、Coordinator以及Bundle。
支持HBase对数据的查询修改以及可视化。
支持对Metastore的浏览,可以访问Hive的元数据以及对应的HCatalog。
另外,还有对Job的支持,Sqoop,ZooKeeper以及DB(MySQL,SQLite,Oracle等)的支持。
