Evaluating map reduce tasks scheduling algorithms over cloud computing infrastructure

Efficiently scheduling MapReduce tasks is considered as one of the major challenges that face MapReduce frameworks. Many algorithms were introduced to tackle this issue. Most of these algorithms are focusing on the data locality property for tasks scheduling. The data locality may cause less physical resources utilization in non-virtualized clusters and more power consumption. Virtualized clusters provide a viable solution to support both data locality and better cluster resources utilization. In this paper, we evaluate the major MapReduce scheduling algorithms such as FIFO, Matchmaking, Delay, and multithreading locality (MTL) on virtualized infrastructure. Two major factors are used to test the evaluated algorithms: the simulation time and the energy consumption. The evaluated schedulers are compared, and the results show the superiority and the preference of the MTL scheduler over the other existing schedulers. Also, we present a comparison study between virtualized and non-virtualized clusters for MapReduce tasks scheduling. Copyright (C) 2015 John Wiley & Sons, Ltd.
