> 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:
