We are living in the modern computer age and using very hi-technology. This is making us to deal the huge amount of data in in-built server storages or through online in the web. Each data is connected with some other data source and it is very tough to estimate the volume of data through digitally. This huge data is called as big data that indicates the amount of data in the range of some terabytes and beyond. Mostly, this type of data is in the form of images, videos and different documents with different structure format. To process and analyse this large amount of data using the technique is called “Hadoop platform”. It is very high speed process and cost effective too.
