Energy Efficiency for Large-Scale MapReduce Workloads With Significant Interactive Analysis

Free registration required

Executive Summary

MapReduce workloads have evolved to include increasing amounts of time-sensitive, interactive data analysis; the authors refer to such workloads as MapReduce with Interactive Analysis (MIA). Such workloads run on large clusters, whose size and cost make energy efficiency a critical concern. Prior works on MapReduce energy efficiency have not yet considered this workload class. Increasing hardware utilization helps improve efficiency, but is challenging to achieve for MIA workloads. These concerns lead one to develop BEEMR (Berkeley Energy Efficient MapReduce), an energy efficient MapReduce workload manager motivated by empirical analysis of real-life MIA traces at Facebook.
