Spark over graphviz (SPARK-1015, SPARK-975)

[jay vyas <ja...@gmail.com>]

Hi spark.

I see there has been some work around graphviz visualization for spark jobs.

1) I'm wondering if anyone actively maintaining this stuff, and if so what
the best docs are for it - or else, if there is interest in an upstream
JIRA for updating the graphviz APIs it.

2) Also, am curious about utilities for visualizing/optimizing the flow of
data through an RDD at runtime and where those are in the existing codebase.

Any thoughts around pipeline visualization for spark would be appreciated.
I see some conversations about it in JIRAs but not sure what the future is
for this , possibly I could lend a hand if there are any loose ends needing
to be tied.
