AbstractThe MapReduce paradigm is now the de facto standard for large-scale data analytics. In this paper we address the resource management issues in MapReduce Cluster. Speculative execution (task backup) plays an important role in resource management. We propose two different strategies and build two models to formulate the backup issue as an optimization problem when the cluster is lightly loaded. Moreover, we present an Enhanced Speculative Execution (ESE) algorithm when the cluster is heavily loaded and adopt the approximate analysis to get an optimal value for the parameter in the algorithm. The simulation results show that the algorithm can reduce the job completion time by 50% while consuming much less resource compared to the naive method without backup.
