Netflow data collected from dedicated probes can be effectively utilized for observing critical links. Data from routers can provide a network-wide view of the traffic and can be made useful in the fields like performance monitoring, capacity planning, accounting and security. This paper comprises of a survey on network traffic analysis using Apache Hadoop MapReduce framework and a comparative study of typical MapReduce against Hadoop Pig which is a platform for analyzing large data sets. It also provides an ease of programming, thereby optimizing opportunities and enhancing extensibility
