3. What is Hadoop?
Big Data Hadoop Training: Hadoop is a free, Java -based programming
framework that supports the processing of large data sets in a distributed
computing environment. It is part of the Apache project sponsored by the
Apache Software Foundation. Hadoop makes it possible to run applications on
systems with thousands of nodes involving thousands of terabytes of storage
capacity. Its distributed file system facilitates rapid data transfer rates among
nodes and allows the system to continue operating uninterrupted in case of a
node failure. This approach lowers the risk of catastrophic system failure, even
if a significant number of nodes become inoperative.

4. Why Hadoop?
• Large Volumes of Data: Ability to store and process huge amounts of variety (structure,
unstructured and semi structured) of data, quickly. With data volumes and varieties
constantly increasing, especially from social media and the Internet of Things (IoT), that’s a
key consideration.
• Computing Power: Hadoop’s distributed computing model processes big data fast. The more
computing nodes you use, the more processing power you have.
• Fault Tolerance: Data and application processing are protected against hardware failure. If a
node goes down, jobs are automatically redirected to other nodes to make sure the
distributed computing does not fail. Multiple copies of all data are stored automatically.
• Flexibility: Unlike traditional relational database, you don’t have to process data before
storing it, You can store as much data as you want and decide how to use it later. That
includes unstructured data like text, images and videos etc.
• Low Cost: The open-source framework is free and used commodity hardware to store large
quantities of data.
• Scalability: You can easily grow your system to handle more data simply by adding nodes.
Little administration is required.
