Hadoop, on the other hand, is an open-source data framework that is meant for storing and analyzing Big Data. Developed in Java, Hadoop mainly consists of two core components: HDFS and MapReduce.
Hadoop Distributed File System (HDFS) is responsible for storing huge amounts of data efficiently and in a fault-tolerant manner. It stores the data across huge distributed clusters. MapReduce is Hadoop's processing engine, and it is meant for parallel computation of the data.
