The main components of Hive's architecture include: 1) Client (HQL or Thrift), responsible for sending queries to the Hive Metastore and processing results; 2) Hive Metastore, which manages metadata and provides a unified view of data across various data warehouses; 3) Execution Engine, responsible for executing queries against the data stored in Hadoop Distributed File System (HDFS); 4) Data Warehouse/Database storing the actual data.
