--------------------------------------

             Summary: Plan dot file can display more infromation
                 Key: CRUNCH-519
                 URL: https://issues.apache.org/jira/browse/CRUNCH-519
             Project: Crunch
          Issue Type: Improvement
          Components: Core
            Reporter: Ron Hashimshony
            Assignee: Josh Wills


The current plan dot file display nicely the jobs, with nice names and arrows.
However it does not explain how the planner decided on the reducers number, which is based
on the input data size, scale factor and desired size per reducer.

I suggest adding this information to the dot file.
An addition to the DotfileWriter class can do this easily.
