Hadoop is an open-source framework designed for distributed storage and processing of large data sets across clusters of computers using simple programming models. It is a key technology in big data analytics, providing a scalable and fault-tolerant architecture.

Features of Hadoop:

• Scalable architecture that can handle petabytes of data across many machines.
• Distributed storage through the Hadoop Distributed File System (HDFS).
• Ability to process large data sets in parallel using MapReduce programming model.
• High fault tolerance with automatic data replication across nodes.
• Support for various data formats including structured, semi-structured, and unstructured data.
• Integration with other big data tools such as Apache Hive, Apache Pig, and Apache HBase.

Check the version of Hadoop run these command on VM:
