Which Hadoop component is designed for batch processing?

• A. Apache HBase
• B. Apache Spark
• C. Map/Reduce Framework
• D. Apache Hive

Answer: (C)

The Map/Reduce Framework is the correct answer because it is specifically designed for batch processing of large data sets in a distributed computing environment. The framework works by breaking down a larger data processing task into smaller subtasks that can be executed in parallel across a cluster of computers. The 'Map' function processes and filters input data, producing intermediate key-value pairs, while the 'Reduce' function aggregates and condenses the results from the 'Map' phase, yielding the final output. This architecture is particularly well-suited for handling extensive data operations that need to be processed in bulk, rather than in real-time or interactive queries. The efficiency of Map/Reduce comes from its ability to distribute workloads, fault tolerance, and its scalable nature, which makes it a foundational component of the Hadoop ecosystem for batch processing tasks. Other components listed, such as Apache HBase, Apache Spark, and Apache Hive, serve different purposes. HBase is designed for real-time read/write access to large datasets and is leveraged for applications that require low-latency access. Spark, while it can perform batch processing, is mainly known for its in-memory processing capabilities, which makes it suitable for both batch and real-time processing. Hive, on the other hand, transforms queries into Map
