Analysis and Study on under Cloud Computing Multiple Sets of Fault Tolerance Strategy Architecture of MapReduce

This paper presents a Multiple Sets of Fault Tolerance Strategy of MapReduce,improve Hadoop MapReduce framework,between TaskTracker node in the same cabinet group relationship added multiple sets relations,it can short the time of founding the failed node,at the same time,reduce the load of JobTracker node,bandwidth utilization and network congestion.The experimental results show that Multiple Sets of Fault Tolerance Strategy of MapReduce improved the efficiency of MapReduce.
