HADOOP

Characteristics and Environment of Hadoop

Open-source project managed by the Apache Software Foundation.

Framework for Big Data that divides data and computation across nodes in a cluster.

Ensures fault tolerance through data replication across multiple nodes.

Composed of core modules:

HDFS, YARN, MapReduce, and Hadoop Common.

Works on Linux-based environments (commonly Ubuntu or CentOS).

Built for horizontal scalability: easily adds new nodes without redesigning architecture.
