[jira] [Commented] (CRUNCH-105) Add generation of Graphviz dot
files to describe the pipeline job plan
[ https://issues.apache.org/jira/browse/CRUNCH-105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13487248#comment-13487248 ]
Josh Wills commented on CRUNCH-105:
-----------------------------------
G-- looks super cool. How do I use it, as a client? It seems like I would want access to the DOT file w/o having to actually kick off a run.

> It could be very useful to have the ability to create Graphviz[1] dot files[2] based on the outcome of the planner. This could facilitate visualizing the full graph of DoFns as well as jobs and mappers and reducers in a Crunch pipeline.
