Hue Installation | Statinfer

Hue aggreates the most common Apache Hadoop components into a single interface and targets the user experience. Its main goal is to have the users âjust useâ Hadoop without worrying about the underlying complexity or using a command line.

Hue supports a file and job browser such as Hive, Pig, Impala, Spark, Oozie, HBase, Solr, Sqoop2, ZooKeeper and more.

Hue comes with an SDK that let you reuse the Hueâs libraries, so you can start building apps on top of Hadoop.
