> 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: https://github.com/semihsalihoglu/graft
