基于Hadoop集群的加权循环算法的研究

调度问题是目前云计算研究中的热点问题,其目的是研究如何协同云计算资源,使其能最大化利用.Hadoop是目前流行的开源云计算平台.针对Hadoop自带的作业调度算法的不足,研究和实现了基于优先级的加权循环算法.该算法能够区分用户服务等级,保证系统资源不被服务等级高的用户长时间占有,保证系统资源得到合理的利用.最后,对该算法进行实验及性能分析,验证该算法能够提高系统的整体效率和减少了相应时间,避免资源浪费.

Research on Weighted Round Robin Algorithm Based on Hadoop Clusters

This paper proposes a design and implementation priority based weighted round robin algorithm based on Hadoop clusters.It can clearly distinguish the level of customer service,while ensuring high priority was not subject to a small majority of users sharing system resources and making the best use of resources.Finally,carried on experiment to the algorithm and analyzed the funcation,verified the algorithm to improve the performance of the system and set the appropriate for users and avoid the waste of resources.
