Deriving Job Completion Reliability and Job Energy Consumption for a General MapReduce Infrastructure from Single-Job Perspective

MapReduce as a master-slave infrastructure consists of two master-side severs and a large number of slave-side working nodes. In this paper, we derive a job completion reliability (JCR for short) model from a single-job perspective for a general MapReduce infrastructure in which no redundancy scheme is adopted on the master side, and a cold-standby scheme is employed on the slave side. Without loss of generality, the JCR model is derived based on a Poisson distribution. In addition, we calculate the corresponding job energy consumption (JEC for short). Through the simulation and analytical results, MapReduce managers and service providers can comprehend how this infrastructure behaves and how to improve the infrastructure so as to achieve a more reliable and energy-efficient MapReduce environment.
