    STEAMEngine: Driving MapReduce Provisioning in the Cloud

    MapReduce has gained in popularity as a distributed data analysis paradigm, particularly in the cloud, where MapReduce jobs are run on virtual clusters. The provisioning of MapReduce jobs in the cloud is an important problem for optimizing several user as well as provider-side metrics, such as runtime, cost, throughput, energy, and load. In this paper, we present a provisioning framework called STEAMEngine that consists of provisioning algorithms to optimize these metrics through a set of common building blocks. These building blocks enable spatio-temporal tradeoffs unique to MapReduce provisioning: along with their resource requirements (spatial component), a MapReduce job runtime (temporal component) is a critical element for any resource provisioning algorithm. We also describe two novel provisioning algorithms - a user-driven performance optimization and a provider-driven energy optimization - that leverage these building blocks. Our experimental results based on an Amazon EC2 cluster and a local 6-node Xen/Hadoop cluster show the benefits of STEAMEngine through improvements in performance and energy via the use of these algorithms and building blocks.
