Name the main components of Hadoop.
Answer
The main components of Hadoop are the Hadoop Distributed File System (HDFS) for storage and MapReduce for processing.
Other key components include YARN (Yet Another Resource Negotiator) for cluster resource management. HDFS provides fault-tolerant distributed storage using a NameNode-DataNode architecture, MapReduce provides the parallel processing engine using Map and Reduce phases, and YARN decouples resource management from job scheduling so multiple processing frameworks (Spark, Hive, MapReduce) can share the same cluster.
