A MapReduce Framework for an Effective Scheduler Based on the Job Size in Hadoop

Madhumala R B, Ravichandra Y B

Abstract: The MapReduce framework and its open source implementation in Hadoop is existing as an standard for Bigdata related processing in industry and academies. When a bunch of jobs are simultaneously submitted together to a MapReduce cluster, bunch of jobs will compete for available resources by this the overall system performance may go down, this is because in MapReduce cluster different kinds of workload is shared among multiple users. Existing scheduling algorithms which are supported by Hadoop always cannot guarantee good average response time with different workloads. Therefore it is a challenging ability to design an effective scheduler which can work with shared MapReduce cluster. To solve this problem we propose a new hadoop scheduler which works on the different workload patterns and reduces overall execution time and job response time by dynamically tuning the available resources that is shared among multiple users and scheduling algorithm for each user. The experimental results are obtained from CloudEra shows that proposed scheduler reduces the average job response time under different workloads that are compared with existing Fair and FIFO Scheduler.
