Which technology is NOT considered part of Hadoop Core?

• A. HDFS
• B. YARN
• C. Hive
• D. MapReduce

Answer: (C)

Hive is not considered part of Hadoop Core. Hadoop Core primarily consists of three main components: HDFS (Hadoop Distributed File System), which handles the storage of data; YARN (Yet Another Resource Negotiator), which manages resources and scheduling tasks; and MapReduce, which is the processing paradigm used to analyze data. While Hive is built on top of Hadoop and is used for data warehousing tasks, enabling SQL-like querying over data stored in HDFS, it operates as an additional layer rather than being a fundamental part of the core architecture. Thus, it provides useful functionality for data analysis and querying but does not belong to the foundational components that constitute Hadoop Core itself. Understanding the distinction between core components like HDFS, YARN, and MapReduce versus additional tools like Hive is essential for grasping the overall architecture and technology stack of Hadoop.
