             Summary: Giraph Debugger
                 Key: GIRAPH-905
                 URL: https://issues.apache.org/jira/browse/GIRAPH-905
             Project: Giraph
          Issue Type: New Feature
            Reporter: Jaeho Shin


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
