What is Apache Hadoop? ; Apache Hadoop is an open source software framework for running distributed applications and storing large amounts of structured, semi-structured, and unstructured data on clusters of inexpensive commodity hardware. Hadoop is credited with democratizing big data analytics. Before Hadoop, processing and storing large amounts of data was a challenging and expensive task that required high-end, proprietary hardware and software. Hadoop’s open-source framework and its ability to run on commodity hardware made big data anal ...

You can’t have a conversation about Big Data for very long without running into the elephant in the room: Hadoop. This open source software platform managed by the Apache Software Foundation has proven to be very helpful in storing and managing vast amounts of data cheaply and efficiently. But what exactly is Hadoop, and what makes it so special? Basically, it’s a way of storing enormous data sets across distributed clusters of servers and then running “distributed” analysis applications in each cluster. ...
Here's an overview of how Hadoop works: 1. Hadoop Distributed File System (HDFS): - HDFS is the storage component of Hadoop. It divides large files into smaller blocks (typically 128 MB or...
