Hadoop Cluster of Fair Scheduling Lgorithms to Improve and Achieve
Peng Zhang · Computer Knowledge and Technology · 2012
Hadoop is increasingly using for enterprises as an open source implantation of MapReduce.But when Hadoop clusters occur more small job,using its built-in scheduling will reduce the overall system throughput.In this paper,put forward a delay scheduling algo rithm base on fair scheduling aiming at its defect.By setting a delay to ensure the local nature of the data.Experimental results show that the new scheduling algorithm can improve overall system throughput.
