摘要
Hadoop在企业界逐步得到了广泛的应用,其子项目Hadoop分布式文件系统(HDFS)的安全问题就表现得日益突出。在研究了Kerberos以及RBAC模型的基础上,提出了基于令牌的认证机制、基于令牌的访问控制机制以及基于域和角色的访问控制模型以解决HDFS的认证与授权问题。
As a result of widespread application of Hadoop in industry during these years,Security concerns of HDFS,Hadoop＇s subproject,are becoming increasingly serious.Based on the research on such security mechanisms as Kerberos,RBAC model and so on,the paper proposes such solutions as Authentication Based on Token,Access Control Based on Token,Access Control Model based on Domain and Role,to figure out the problems of authentication and authorization.
