[Hadoop Hue] the Web UI for Hadoop

hadoop hue

Hadoop Hue is an open sourced user interface for Hadoop components. It is easy to use and accessible from a browser and it allows developers to increase productivity on their Hadoop projects.

Hue is an open sourced project developed by Cloudera. They contributed this project to make it easier for new and old Hadoop developers to access data and different Hadoop tools.

The cool thing about Hadoop Hue is that you can get a quick grasp of the essentials of Hadoop technologies like Apache Pig, Hive, MapReduce, Sqoop, Cloudera Impala, HBase, etc. You have the advantage to  browse all your files on HDFS (Hadoop Distributed File System) and can query them through Hive, Apache Pig or Impala (SQL on Hadoop)

Here is how it looks like:

File Browser (Files on HDFS)

On the right top corner, you will see a document icon where you can search all of the files on HDFS. Files are organized by hierarchy. It starts with and “/user/” directory and the rest of the folders will be within it . If you have the appropriate access, you can add, delete, modify, download files, etc.

Final Thoughts

While working in Hadoop, Hue will be one of the tools you will be interacting the most on a daily basis. Having the visual aspect is always a big plus when working with Hadoop technologies such as Pig, Hive, Oozie, HBase, etc.
