> Project: Giraph
> Issue Type: Bug
> Reporter: Dionysios Logothetis
> Priority: Major
>
> Occasionally, BspServiceMaster fails to detect that a worker finished a
> superstep (e.g. input superstep, or a compute supestep). As a result, the job
> may get stuck as the master keeps waiting for all workers to finish.
