Free Online Demo On Hadoop and spark

Hadoop is an open-source distributed big data processing framework that manages data processing and storage for big data applications running in clustered systems, i.e., it’s a file system for storing data from different sources in big data frameworks. Its architecture is based on a node-cluster system, with all data shared across multiple nodes in a single Hadoop cluster. Consequently, Hadoop is a framework that enables the storage of big data in a distributed environment so that it can be processed in parallel.
