Study of Security Mechanism based on Hadoop

Hadoop,as an open-source cloud computing framework,is increasingly applied in the business world,while the weakness of security mechanism now becomes one of the main problems hindering its development.This paper first summarizes the traditional network security issues and mechanisms,analyzes the security problems of cloud computing,then based on description of its operating mode,gives Hadoop's security requirement,and finally through study of Hadoop's security mechanism and analysis of security risk in its current version,proposes some corresponding solutions.All these could provide certain technical supports for the enterprises in their Hadoop applications with new security needs.
