Large-scale MapReduce clusters that routinely process petabytes of unstructured and semi-structured data represent a new entity in the changing landscape of clouds. A key challenge is to increase the utilization of these MapReduce clusters. In this work, we consider a subset of the production workload that consists of MapReduce jobs with no dependencies. We observe that the order in which these jobs are executed can have a significant impact on their overall completion time and the cluster resource utilization. Our goal is to automate the design of a job schedule that minimizes the completion time (makespan) of such a set of MapReduce jobs. We offer a novel abstraction framework and a heuristic, called BalancedPools, that efficiently utilizes performance properties of MapReduce jobs in a given workload for constructing an optimized job schedule. Simulations performed over a realistic workload demonstrate that 15%-38% makespan improvements are achievable by simply processing the jobs in the right order.
