What Is Hadoop?
Hadoop is an open-source framework developed by Apache that enables the processing of large data sets across clusters of computers. It was designed to scale from a single server to thousands of machines, each offering local computation and storage.
Hadoop’s core components include the Hadoop Distributed File System (HDFS), which stores data across multiple nodes, and the MapReduce programming model, which enables data processing. Hadoop’s architecture is designed in a way that it can deal with failures at the application layer itself, making it highly resilient to faults.
Hadoop has been widely adopted by many organizations due to its proven ability to handle petabytes of data. However, it’s not without its challenges. The batch processing nature of Hadoop’s MapReduce model can lead to latency issues, especially when dealing with real-time data processing.
