Abstract: In this era of Big Data, organizations collect massive volumes of data in order to derive insights for making decisions. To handle and process big data, new architectures and technologies were evolved. Out of these technologies, Hadoop framework has been adopted by many organizations for storing and processing large complex data. Hadoop framework is an open source technology which has not prioritized security in its initial stages of development. Originally Hadoop has developed to work behind the firewall. But, due to widespread acceptance of Hadoop by many enterprises has provoked most of the cloud distributors for providing Hadoop-as-a-service. This paper firstly describes Hadoop framework, then Hadoop execution on OpenStack and finally focuses on the recent efforts taken by various researchers to provide security in Hadoop framework.
