Metastore is the central repository of Apache Hive data warehouse. It stores metadata for Hive tables (like their schema and location) and partitions in a relational database. It provides client access to this information using Metastore service. This test reports the total number of databases, partitions and tables used in the Metastore.
Target of the test : Apache Hive
