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

             Summary: Visualizations of some important internal/intermediate pipeline planning
states
                 Key: CRUNCH-438
                 URL: https://issues.apache.org/jira/browse/CRUNCH-438
             Project: Crunch
          Issue Type: Improvement
          Components: Core
    Affects Versions: 0.8.3, 0.10.0
            Reporter: Christian Tzolov
            Assignee: Christian Tzolov


To improve the understability of the pipeline planning stages it would help to visualize some
intermediate planning states like:
- PCollection lineage. (visualizing the output-pcollection-targets structure) 
- MSCRPlanner's planning Graphs before and after the split up of dependent GBK nodes
- RTNode hierarchy along with the Input and Output configurations as persistent in the Configuration
before the execution of the pipeline. 

Most of the information can be intercepted in the MSCRPlanner#plan()  method.
