Paolo Castagna commented on GIRAPH-77:

Hi Avery, I am still learning and stepping into the Apache Giraph source code 
(fortunately, it isn't that big) :-)
Do you or Jakob have a favorite stack to do that? Jetty/Netty?, JAX-RS?, etc. 
Any specific web framework and/or template engine? Something small, something 
to minimize dependencies, ... I tend to use Jetty with plain servlets and 
Velocity. But I am open to suggestions.

Ideally, we could/should publish JSON and render HTML pages client side (once 
again, I accept suggestions on JavaScript frameworks).
I must warn you though, I am not a web|graphic designer (and I know my limits 
on the UI front). But, once the basic functionalities are in place and the 
correct data is available, I am sure some good web designer will fix that up.

Coming back to your question, with some guidance, yes. 
I would like to give it a shot and I have time to dedicate to Apache Giraph.

> It would be nice if the coordinator worker had a web interface that showed 
> progress, splits, etc. during job execution. Right now it would duplicate 
> information currently being exposed through task status, but with the move to 
> YARN, it will be a necessity.  It would be great if we could do this in a 
> modern way to avoid the screen-scraping, etc. currently used to get 
> information from most other Hadoop project's web interfaces.  The coordinator 
> could announce its address at the beginning or via status updates.
