Ganeshbabu Nelamangala commented on CRUNCH-304:
-----------------------------------------------
Yes, that should work. If cleanup is available below should work to solve our
issue.
1. generate the DOT diagram for the targets pipeline holds then will
2. do a cleanup() to clear the targets.
3. call done() which performs cleanup to clear any temporary folder it creates.
[~mkwhitacre] please suggest if this is good.
> MRPipeline.plan() does not clear up the temporary hadoop-<username> folder it

> 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.
