大数据环境下MapReduce准入控制的设计与实现

为了保证Hadoop平台的安全性,确保执行MapReduce作业的TaskTracker节点符合Hadoop平台的安全管理要求,杜绝非法用户对TaskTracker节点访问并对其分配任务,提出了一种对JobTracker节点进行身份认证的方法,设计实现了对JobTracker节点进行身份认证的认证体系。该认证体系主要是基于802.1x进行准入控制,重点分析了MapReduce分布式计算的流程,提出了总体设计方案,完成了相关模块的配置实现,最终结果显示只有通过认证的JobTracker才能通过交换机的可控端口给相应的TaskTracker节点分配任务,有效地避免了非法用户的访问,增强了Hadoop平台的安全性、可靠性,为建设安全的大数据环境提供了很好的技术支持。

Design and Implementation of Mapreduce Access Control in Big Data Environment [JZ)][HS)]

In order to ensure the security of Hadoop platform,to ensure that the TaskTracker node of the MapReduce operation is in accordance with the safety management requirements of the Hadoop platform, Put an end to the illegal users access to TaskTracker node and the assigned task, A method of authentication for JobTracker node is proposed, Design and implementation of the authentication system for JobTracker nodes. The certification system is mainly based on 802.1x performs admission control, Focus on the analysis of the process of MapReduce distributed computing, Put forward the overall design scheme, Complete the configuration of the relevant module, The final result shows that the TaskTracker node assignment can be assigned to the corresponding JobTracker node through the control of the switch, Effectively avoid the illegal user access, Enhanced security and reliability of the Hadoop platform, For the construction safety of big data environment provides a good technical support.
