摘要
Abstract
The optimisation on MapReduce workflow is mainly achieved by optimising the MapReduce stack.For the problem of MapReduce workload optimisation,first we present the related concept;secondly,we introduce the cost-based optimisation process of MapReduce workflow;then we expound through examples the relation of dataflow dependency and resource dependency in MapReduce workflow.Based on this,we present three MapReduce workflow optimisers and carry out end-to-end evaluation on them.Finally,we evaluate the optimisation overheads of workflow optimisers through experiment and comparatively analyse all three of them.关键词
