HMHS: Hybrid Multistage Heuristic Scheduling Algorithm for Heterogeneous MapReduce System

The scale of data in a MapReduce system is increasing quickly. Thus how to efficiently schedule a set of production jobs has become increasingly important. For a given set of jobs, a well-designed scheduling algorithm can significantly reduce makespan and increase the utilization of clusters. However, there exists very few studies that aim to construct a scheduler that minimizes the makespan of batch jobs in a heterogeneous environment. This paper proposes a heuristic scheduling algorithm called Hybrid Multistage Heuristic Scheduling (HMHS), which tries to solve the scheduling problem by breaking down it into twosubproblems: sequencing and dispatching. For sequencing, we develop a heuristic based on Pri(the modified Johnson’s algorithm). For dispatching, we offer two heuristics Min-Min and Dynamic-Min-Min. Our simulation results on two kinds of workloads demonstrate that every heuristic employed in HMHS contributes to reducing the makespan. As a whole, HMHS improves the performance ranging from 51% to 77% compared to FIFO.
