GroomServerFaultTolerance (Draft)

Introduction

Distributed computing system such as Hadoop[1], and Dryad[2] provide fault tolerance feature to help the system survive over the process crash. It is particular useful when computation requires to finish its execution in long time. Hama, based on the BSP[3] model, is a framework for massive scientific computations, which also requires this feature so that developers and users who exploit this framework can benefit from it. This page serves for providing information on direction how Hama GroomServer fault tolerance would work.
