Hadoop is an open-source software framework used for distributed storage and processing of large datasets across clusters of computers. It was designed to scale up from single servers to thousands of machines, with very large datasets. The core of Hadoop includes HDFS for storage and MapReduce for processing. Hadoop has seen widespread adoption by major companies for applications like advertisement targeting, security analysis, and more. Its advantages include low cost, fault tolerance, and ability to handle large amounts of data.

Doug Cutting
2005: Doug Cutting and Michael J. Cafarella developed
Hadoop to support distribution for the Nutch search
engine project.
The project was funded by Yahoo.
2006: Yahoo gave the project to Apache
Software Foundation.

The name "Hadoop" was given by one of
Doug Cutting's sons to that son's toy
elephant. Doug used the name for his open
source project because it was easy to
pronounce and to Google. If you have 2
minutes, you can watch a video [1] with
more details.
