基于成本的MapReduce工作流优化器
Cost-based MapReduce workflow optimizers
摘要
Abstract
Optimizations at different levels of the MapReduce stack have their advantages and disadvantages. For MapReduce workload optimization problem, related concepts are proposed;cost-based optimization approaches and related technology of MapReduce jobs are introduced and assessed through comparation with RoT;three MapReduce workflow optimizers are presented for cost-based optimization of MapReduce workflows based on dataflow and resource dependencies. Cost-based workflow optimization is evaluated. End-to-end evaluation of the workflow optimizer is described;the advantages and disad-vantages of these three workflow optimizers are analyzed through experimental evaluation of their overhead.关键词
