Hue is a graphical user interface for Apache Hadoop that allows users to operate and develop Hadoop applications from a web browser. Oozie is a workflow scheduler for Hadoop that runs directed acyclic graphs (DAGs) of jobs such as MapReduce, Hive, Pig, and Sqoop. These workflows are defined in XML files and allow complex jobs to be modeled as sequences of actions and control nodes.

4. • Hue is a graphical user interface to operate and develop
applications for Apache Hadoop.
• Hue Server is a "container" web application that sits in between
your Hadoop/Related Ecosystems and the browser.

5. • OOZIE is a Workflow scheduler, which is used to schedule the
Hadoop jobs.
• Oozie Workflow jobs are Directed Acyclic Graphs (DAGs) of
actions.
• Oozie Workflow job is a combination of Action and Control
nodes, where Actions Nodes are Mapreduce, Hive, Pig, Sqoop,
etc.
and Control nodes are Start, END/Kill .. etc.
• All these node declarations are mentioned in workflow.xml file
