Mention key components of Hive Architecture?
Answer / Priyanka Rani
The key components of Hive architecture are: 1) Client: Where users execute HiveQL queries. 2) Hive Metastore: Stores metadata information about tables, partitions, and other objects. 3) Driver: Translates HiveQL into MapReduce jobs. 4) Compiler: Converts HiveQL queries to intermediate forms like Logical Plan (Logical SQL), Physical Plan (Physical SQL), and Vectorized Plan. 5) Execution Engine: Splits the query into multiple stages, executes the map and reduce tasks using MapReduce, and aggregates the results.
