Apache Hadoop is an open-source framework that is designed to store and process large data sets across a cluster of machines and computers. It uses simple programming models to process the given data sets. It provides huge storage space for any type of data, processing power and also the ability to take care of concurrent tasks.  It consists of the following components:

  • Hadoop Distributed File System (HDFS): It is used to store the data.
  • Yarn: It is used for job scheduling as well as a cluster resource management.
  • MapReduce: It is used to perform parallel processing.
  • Common Libraries: They are libraries required by subsystems of Hadoop.
