🔹 What is Hadoop?
Hadoop is an open-source framework that allows for distributed storage and processing of large datasets across clusters of computers. It is designed to handle massive amounts of data efficiently.
🔹 Key Components:
✅ HDFS (Hadoop Distributed File System): Stores large files across multiple machines.
✅ MapReduce: A programming model for processing big data in parallel.
✅ YARN (Yet Another Resource Negotiator): Manages computing resources.
✅ Hive, Pig, Spark: Additional tools for easier data processing.
🔹 Why Use Hadoop?
✔️ Scalable & Cost-Effective
✔️ Handles Structured & Unstructured Data
✔️ Fault-Tolerant & Distributed Processing
