Jaeho Shin updated GIRAPH-905:
------------------------------
Attachment: GIRAPH-905.patch
Here's a patch including all our work. We realize this is a rather large
patch. The debugger consists of four core pieces: 1) the instrumenter, 2) the
GUI, 3) the code generator, and 4) the command-line interface, and this patch
includes all those four. We are open to ideas on how to push this in pieces.
It works readily if you follow the instructions on our GitHub wiki. (We're
still working on some parts of the documentation.)

> Four of us at Stanford (Vikesh Khanna, Semih Salihoglu, Jaeho Shin, and Brian
> Ba Quan Truong) developed a debugger for Giraph, named Graft, and we hope to
> integrate our code into Giraph trunk. It is able to launch Giraph jobs in
> debugging mode to capture traces of certain vertices and MasterCompute at
> particular supersteps, requiring almost no code change by the user. From the
> captured traces, it can generate JUnit tests to replicate the contexts under
> which compute() function was running for the user to reproduce bugs. You can
> read more about it at our GitHub repository:
