Subject [jira] [Updated] (CRUNCH-438) Visualizations of some important internal/intermediate pipeline planning states
Date Tue, 08 Jul 2014 13:59:05 GMT

     [ https://issues.apache.org/jira/browse/CRUNCH-438?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Christian Tzolov updated CRUNCH-438:
------------------------------------

    Attachment: CRUNCH-438.3.patch

Gabriel i think your point makes sense. So i've attached a new patch (v3) that removes the
functionality that writes dotfiles into the PIPELINE_DOTFILE_OUTPUT_DIR folder. Also i've
fixed (hopefully) the spelling names. The debug diagrams will be stored i the following configuration
properties:
* PCOLLECTION_LINEAGE_DOTFILE 
* BASE_GRAPH_PLAN_DOTFILE
* SPLIT_GRAPH_PLAN_DOTFILE
* RTNODES_PLAN_DOTFILE

Would it make sense to enable the 'debug' dotfiles generation only if the pipeliene.enbableDebug()
is set? 
 
Also shall we move all DotfileWriter... clases into a dedicated package? For example: org.apache.crunch.impl.mr.plan.tracke

> 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.
