> For a user, knowing progress of her workflow is always desirable. This ticket
> is to introduce this support to Oozie.
> I know it's a hard problem. For my initial effort, I plan to start with
> simple workflows that do not contain decision nodes or fork/join nodes, i.e.,
> chain type workflows. I plan to use percentage of finished actions as the
> overall wf progress estimate.
> Going forward we can improve the estimation by:
> 1) handle general workflows that contain decision, fork/join nodes;
> 2) incorporate the action level progress into wf level progress estimation to
> make the estimate better. To be more specific:
> In the case of "opaque" actions like pig/hive/jaql where the status can only
> be 0% or 100% (or failure) we plug that value into the overall DAG status of
> 0-100%. If a DAG had say 4 opaque actions, the progress would move in
> discrete steps 0, 25, 50, 75, 100%. For the m/r actions where the JobTracker
> gives values between 0-100% for an action then the overall progress will be
> smoother. We can do same thing for pig/hive/jaql actions as well if they
> expose their own progress info.
