Joint optimization of overlapping phases in mapreduce

Abstract

MapReduce is a scalable parallel computing framework forbig data processing. It exhibits multiple processing phases,and thus an efficient job scheduling mechanism is crucial forensuring efficient resource utilization. This work studies thescheduling challenge that results from the overlapping of the"map" and "shuffle" phases in MapReduce. We propose anew, general model for this scheduling problem. Further,we prove that scheduling to minimize average response timein this model is strongly NP-hard in the offline case andthat no online algorithm can be constant-competitive in theonline case. However, we provide two online algorithms thatmatch the performance of the offline optimal when given aslightly faster service rate.
