Ashish Vaidya commented on OOZIE-906:
-------------------------------------
Oh and the rendering of the graph isn't completely foolproof. If given a
sufficiently complex workflow, my simplistic node placement algorithm can't
guarantee that overlaps won't happen!
> Show runtime job DAG visually in Oozie console/dashboard

> URL: https://issues.apache.org/jira/browse/OOZIE-906
> Project: Oozie
> Issue Type: New Feature
> Reporter: Ashish Vaidya

> Labels: graphical, job_graph, runtime_job_graph
> Attachments: GraphGenerator.java, OOZIE-906.patch, Sample runtime
> DAG.png, graphFRShape.png

> Original Estimate: 504h
> Remaining Estimate: 504h

> The browser based Oozie console (the one currently written in ExtJS) shows
> the following tags when one clicks on a job to see its details:
> - Job Info
> - Job Definition
> - Job Configuration
> - Job Log
> It is desired to add a visual representation of the job DAG. An additional
> tag (likely called Job Graph) will be provided in the above console that
> will, when clicked, show the job workflow diagrammatically.
> The nodes in the graph/diagram will be color coded to represent their current
> state (Red for error/kill/failure, Green for OK and Yellow for the rest; or
> some combination thereof).
> The nodes will have names as provided in the job definition. The nodes may
> also be of different shapes (per action/control node) for better visibility.
> They may also carry some basic info like start time and duration.
> As regards implementation, it will be a server side with an HTTP API URL as
> invoker. The graphing may be done using GraphViz APIs, provided we find those
> to be Apache License compliant.
