Hadoop grew out from the GFS (Google File System) and the cross-platform program was developed in Java. It comprises of four main components

  • Hadoop File System – Stores files on all the cluster systems.
  • Hadoop MapReduce – It handles the processing.
  • Hadoop YARN – It manages the computer systems and the user accessibility.

Hadoop works by dividing the files into blocks and distributing them in a cluster. It then processes the data which makes this form of data analysis much quicker than other means.

Sitting at the core of Hadoop operations is HDFS. It is designed in a way that is readable and portable. It can store data files having the size of terabyte across multiple platforms. HDFS is designed for its portability nature across various platforms and OS. It also works with other file systems like Amazon S3 and Microsoft Azure.
