-----------------------------------
Summary: Show runtime job DAG visually in Oozie console/dashboard
Key: OOZIE-906
URL: https://issues.apache.org/jira/browse/OOZIE-906
Project: Oozie
Issue Type: New Feature
Reporter: Ashish Vaidya
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.
