I am interested in $subject gosc idea and preparing the proposal.
little bit of background:
I am undergrad form Univ. of moratuwa, Sri Lanka.
I did a internship last year at WSO2 [1] during which I did a data
visualization project.
It involves generating visualization gadgets for hadoop job results.
it's integrated to WSO2 BAM 2 alpha [2] release so far.
technologies/frameworks involved where - html5/css, javascript, google
closure tools/lib [3], wireit [4], jqPlot.
let me describe the main use case as I understood it:
1. user launches pig with command line, such as
   pig -x local -webconsole 8085
2. user logs to http://localhost:8085 using a browser
3. emulated console is visible in the web page via which, one can
execute usual grunt commands.
   additional UI elements exist to upload Pig Latin script, configuration, ect.
4. output of each grunt command is formatted using some html/javascript template
   eg:- ILLUSTRATE will out put neat looking html table.
5. special emphasis is given in this project to formatting EXPLAIN command.
   it will generate interactive html elements with additional meta-data.
   eg:- clicking a foreach element will expand it with more visualization.
it would be very helpful if you can clarify some of the question below:
1. did I capture the main requirement of this project in above scenario.
   is there any more required function i missed out?
2. is allowing web interface for grunt too much (out of scope) for this project?
   even thou the project is about plan visualization, i thought this is the
   most elegant way to approach the problem.
3. are the graphics (eg DAG graph) suppose to be generated on browser
side or java side?
   my personal preference is for browser generated, since it will be
easier to make
   them interactive.

(sorry for the resend russell)
any comment/feedback would be appreciated, thanks.

hi russell,
I have submitted a proposal at melange.

I am aware that the pig team has been very busy recently. Hope you’ll
be able to provide some feedback soon. Thanks

Hi, Russell,
You need to
1. send request to [EMAIL PROTECTED] and [EMAIL PROTECTED]
to become a mentor
2. create account at http://www.google-melange.com/gsoc/homepage/google/gsoc2012
3. apply mentor to Apache in google-melange
4. let me know your google-melange so I can update Melange id for you

Thanks,
Daniel

Do we have a committer who's signed up to mentor this issue?
Russ can't according to apache's guidelines for gsoc (though he can
certainly help advise / review code / etc -- just not be an official
apache foundation rep to google regarding progress of the project)

Ah, ok. I've been noodling on the problem and don't know Pig internals well
enough to figure out a clean way to get at the data that is needed for this
task. Someone familiar with HCatalog and how y'all are handling accessing
Pig ILLUSTRATE data there would be a more appropriate mentor.

Seems they changed the rule this year. Last year non-committer can
mentor. I can be the backup if no one else want to mentor this.

Hi,
Thanks for the replies and feedback.
I was not aware of the mentor situation. I hope that can be resolved.
I have made the proposal public, so you should able to see it without
registration [1].

@Daniel, in reply to melange comment
Reason why I am suggesting doing a web interface, instead of including
a command like “explain -script 111.pig -graphics” :-
  1.If we make a new java swing window pop up and show the plan
diagram, users who are using it via remote accesses (SSH) will have to
go through extra trouble to use it.

  2. It will be easier to integrate to a web site of a cloud service
provider (e.g.:- can be exposed via amazon’s web console).

  3. Room for feature expansions. This web UI can be extended to
show other important information. For example one can add a side bar
showing structure of the working hadoop file system (much like
NERDtree).

Should I modify the proposal by adding a section on comparison of java
GUI approach and web approach?
Thanks, and feedback is much appreciated.

Sorry for the delay, I am going over this now. I hope someone will step up to mentor-mentor me, as I think this is important work.

As to the merits of a web application:

1. It is easier to serve JSON containing ILLUSTRATE data than it is to draw
primitives in swing. Pages can be served with a lightweight web server.
This server could get access to data from a modified Pig/Grunt in JSON
format, or simply parse Grunt's output using the 'tee' command.

Once the JSON is out of Grunt, there are numerous diagramming libraries for
web applications, such as WireIT <http://neyric.github.com/wireit/> (great
example here for XProc <http://feedscape.appspot.com/>), or you can roll
your own using d3.js or Raphael.js for drawing and something like
jGraphViz<http://jgraphviz.sourceforge.net/>for layout.  You seem to
be familiar with them, and that is great!

2. I agree a web app has more potential.  We want the ILLUSTRATE diagram
feature picked up by Elastic
MapReduce<http://aws.amazon.com/elasticmapreduce/>and Mortar
Data <http://mortardata.com/#!/easy_hadoop>.

3. I agree that many more people will be thrilled to work on a web app than
a Swing or Eclipse application. See: PigPen.
As to the proposal, I have this feedback:

I would focus on the functionality demonstrated in Figure 1 of the PigPen
SIGMOD paper <http://research.yahoo.com/files/paper_5.pdf>: the
visualization of data-flows.  There are enough issues with ILLUSTRATE
itself and getting the presentation right that this is a lot of work.  For
instance, when records are long or complex... there is meaty work to
getting the presentation/visualization done well.  It will be fun!

If you do go for a full-blown IDE, I suggest you do it as a stretch goal.
In doing so, we should be cognizant of the work Mortar Data is doing in
this area. You might try coordinating with them if that is possible.  Be
aware that this is a large project.

There are existing javascript IDEs such as Cloud 9 <http://c9.io/>
(source<https://github.com/ajaxorg/cloud9>)
you can use as a starting point for an in-browser editor. You could plug-in
your ILLUSTRATE functionality to something like this.
I would encourage you to re-scope your proposal to focus on developing an
in-browser visualization of illustrate - with sample records, and then
after it stands on its own on integrating with an existing editor like
cloud9.

I apologize for the delay in my response, and I am excited about this
project and look forward to helping!

Thanks for the reply. Unfortunately I saw it only after the proposal
edit deadline has passed.

>I would focus on the functionality demonstrated in Figure 1 of the PigPen SIGMOD paper
I’ll start reading the paper.

>There are existing javascript IDEs such as Cloud 9 (source)
I am familiar with online IDEs. As I mentioned briefly in the
proposal, I was involved in initializing such a project called ‘gadget
ide’ [1] at WSO2. It is a graph based IDE aimed at dashboard authoring
via specifying data flows, which is a fairly large project (8000+
JavaScript SLOC).

> If you do go for a full-blown IDE, I suggest you do it as a stretch goal
Of cause, I am planning to be more focused on the visualization of
commands. I have mentioned the IDE, only as a possible future
extension. I didn’t include it in the project timeline, but if time
allows I am happy to attempt it. But as you have mentioned, the
visualization part itself is considerably large project.

>I would encourage you to re-scope your proposal
I was expecting EXPLAIN to be the major problem. I wasn’t anticipating
ILLUSTRATE to be hard command to visualize. If so, I’d like to
re-scope the project as you have suggested. How about completing the
ILLUSTRATE before the mid evaluation, and pushing down the plan
visualize to second phase? Will that allocation be enough? I may have
to cut back a little on the interactive features of the graphs. Please
provide your suggestions on this matter.

I am aware that the team is busy with 0.10, so thanks for taking time
to provide feedback.
