Explain HCatalog Architecture in Brief?
Answer / Nishu Agrawal
HCatalog Architecture consists of the following components: Data Catalog, Metadata Store, and SQL Access Layer. The Data Catalog manages metadata for data stored in Hadoop clusters. The Metadata Store stores metadata about tables and views, including their schema and location. The SQL Access Layer provides SQL-like access to the data through a variety of clients, such as Hive, Pig, and Impala.
