Big Data and Hadoop-a Study in Security Perspective

Big data is the collection and analysis of large set of data which holds many intelligence and raw information based on user data, Sensor data, Medical and Enterprise data. The Hadoop platform is used to Store, Manage, and Distribute Big data across several server nodes. This paper shows the Big data issues and focused more on security issue arises in Hadoop Architecture base layer called Hadoop Distributed File System (HDFS). The HDFS security is enhanced by using three approaches like Kerberos, Algorithm and Name node.
