Hadoop is an open-source framework used for storing and processing large datasets in a distributed computing environment. It enables organizations to handle big data efficiently by using a cluster of computers. Key components of Hadoop include: 1. **Hadoop Distributed File System (HDFS)**: A scalable and fault-tolerant file system for storing data across multiple machines. 2. **MapReduce**: A programming model for processing large datasets in parallel across a Hadoop cluster, dividing tasks into smaller, manageable chunks. 3. **YARN (Yet Another Resource Negotiator)**: Manages and schedules resources in the Hadoop ecosystem, allowing multiple applications to run concurrently. ### Key Features: - **Scalability**: Can easily scale to accommodate increasing data volumes. - **Fault Tolerance**: Data is replicated across nodes, ensuring availability in case of hardware failures. - **Cost-Effectiveness**: Uses commodity hardware to store and process data. ### Use Cases: Hadoop is commonly used for data warehousing, big data analytics, machine learning, log processing, and data archiving across various industries. read less
