This study comprises of the introduction in which the Big Data is entailed in addition to this is its features and classification. Then this study talks about the hadoop and its architecture plus the components used in hadoop like HDFS, Map Reduce, Pig, Hive, Hbase, and Sqoop. In the conclusion part — a global valuation is tailedup.
