A SURVEY ON BIG DATA CONCEPTS AND HADOOP MAPREDUCE ALGORITHM

In any engineering field the data associated with knowledge is important one for taking decisions for solving problems in the current system development. In current scenario Organization are supposed to work with huge amount of data. Based on those data a nalysis, predictions, manipulations are made. Replicas of blocks are created to improve the Redundancy in distributed system. A deep understanding is needed inorder to remove some drawbacks in these fields.
