Micah Whitacre commented on CRUNCH-304:
---------------------------------------
Yeah the boolean force was probably the wrong thing to suggest on done.
Actually looking at the code why shouldn't plan() automatically call cleanup()?
If someone was to follow the flow "plan + run" or "plan + done" the targets
would get recreated right and everything would complete successfully.

> As a user i just want to run MRPipeline.plan() to retrieve the
> PlanningParameters.PIPELINE_PLAN_DOTFILE for the current pipeline
> configuration. However it appears that since we don't actually call run(),
> the Map that is created to hold outputTargets still has items in it, and the
> cleanup() method will not execute under the condition of having elements in
> it, to delete the tmp directory that gets created when creating a new
> MRPipeline object. Since we don't really want to execute the code if we just
> want to create a plan then I don't know how we can cleanup this Map.
> Basically the temporary hadoop folders left behind is our problem.
