Christian Tzolov updated CRUNCH-438:
------------------------------------
Attachment: CRUNCH-438.patch
Attached is an initial prototype which implements 3 dotfile writers:
1. DotfileWriterPCollectionLineage - visualizes pcollection leneage
2. DotfileWriterGraph - visualizes the planning graph and components split
3. DotfileWriterRTNodes - visualize the RT nodes, inputs and outputs as
de-seriazlied from the Configuration properties.
All writers inherit from a common CommonDotfileWriter
The interception is hardcoded into MSCRPlanner#plan() method using the LOG.info
to print the result dotfile visualizations.
- Addition getters were added to the RTNodes to access the internal attributes
- CrunchOutputs OutputConfig and CrunchOutputs.getNamedOutputs() methods have
been extended to make them accessible in the dotfile writer.

> 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.
