Workflow Visualization
----------------------
Key: OOZIE-576
URL: https://issues.apache.org/jira/browse/OOZIE-576
Project: Oozie
Issue Type: New Feature
Reporter: Jacob Perkins
Priority: Minor
An oozie workflow can naturally be described with a directed graph. It should
be possible to create a visual representation of an oozie workflow as such by
parsing the workflow definition, resolving any references to sub-workflows, and
creating a nested set of classes that describe the full workflow. This
description could then be serialized as json and visualized with a javascript
library like d3.js (or something along those lines) for display and possibly
even interaction.
Important details here include displaying hierarchy (top-level workflow vs.
sub-workflow) in a clear way and distinguishing between other types of actions
(java, pig, fs, etc..).
