•Hadoop Distributed file system (HDFS™): A distributed file system that has high-throughput access to application data.

•Hadoop Map Reduce: this is a YARN-based system for multiprocessing of huge datasets.
Advantages of Hadoop

•Hadoop framework permits the user to quickly write and take a look at distributed systems. it's economical, and it automatic distributes the data and work across the machines and successively, utilizes the underlying correspondence of the CPU cores.
