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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
