Getting started with Oozie Eclipse Plugin

Components of the Editor


  1. The Workflow area is an empty white space where workflow nodes and connections are placed.
  2. The Palette holds editing and node creation tools. Nodes are categorized into three categories: Control Nodes, Action Nodes and Extended Action Nodes.
  3. The Properties sheet holds the properties of the currently selected items.
  4. The Outline page is a kind of a summary of the workflow contents. There are two views: the outline view and the overview view. Each gives different kinds of shortcuts to reach and find workflow components.


  5. The Action bar holds shortcuts for useful actions: undo/redo, grid and snapping options, nodes alignment options, and zooming options.

Create a new workflow

  1. Go to File -> New -> Other... or press <Ctrl+N>


  2. Under "Apache Oozie" category, select "Apache Oozie Workflow" wizard and press Next >

    1. What version of the plugin do you have?

      Have selected "File -> New -> Other..." (starting from the File menu), then written "Apache Oozie Workflow" as a filter text in the Wizards window?

  3. workflow.workflow is set by default. workflow.xml would be better to use.
