基于优先级权重的Hadoop YARN调度算法
Hadoop YARN Scheduling Algorithm Based on Priority Weight
摘要
Abstract
In order to solve the problem that the existing scheduling task scheduler Hadoop can not depend on the degree of urgency task allocation of resources. We mainly research the resource scheduling mechanism in YARN ( Yet Another Resource Negotiator ) , improved the original capacity scheduler and proposes abased on priority weighted Hadoop YARN scheduling algorithm-weight scheduler based on priority. Firstly, setting queue priority for leaf queue, combining with the queue resource utilization and queue priority to select queue;Secondly, the initial of applications re-set its priorities size, by waitting time to judge whether to update the weight, according to the weight to sort the applications in the selected queue. The experiment shows that comparing with the existing scheduling algorithm, this algorithm has the advantage on the execution time by 141 s and waiting time by 34. 5% decreasing, ensure the user to perform a task relatively fair, improve the overall satisfaction of users.关键词
