Xianqing Yu, Peng Ning, Mladen A. Vouk.  2014.  Securing Hadoop in cloud. HotSoS 2014 Symposium and Bootcamp on the Science of Security. :ArticleNo.26.

Hadoop is a map-reduce implementation that rapidly processes data in parallel. Cloud provides reliability, flexibility, scalability, elasticity and cost saving to customers. Moving Hadoop into Cloud can be beneficial to Hadoop users. However, Hadoop has two vulnerabilities that can dramatically impact its security in a Cloud. The vulnerabilities are its overloaded authentication key, and the lack of fine-grained access control at the data access level. We propose and develop a security enhancement for Cloud-based Hadoop.
