What is HUE?

HUE=Hadoop User Experience

Hue is an open source Apache Hadoop UI system, evolved from Cloudera Desktop, and finally Cloudera contributed it to the Hadoop community of the Apache Foundation, which is based on the Python Web framework Django.

By using Hue, we can interact with the Hadoop cluster on the Web console on the browser side to analyze and process data, such as manipulating data on HDFS, running MapReduce Job, executing SQL statements of Hive, browsing HBase databases, and so on.
