bowenli86 opened a new pull request #8205: [FLINK-12238] [TABLE/SQL] Support database related operations in GenericHiveMetastoreCatalog and setup flink-connector-hive module URL: https://github.com/apache/flink/pull/8205 ## What is the purpose of the change This PR creates GenericHiveMetastoreCatalog which implements ReadableWritableCatalog. It's designed to persist all Flink streaming and batch metadata by using Hive metastore as a persistent storage. Add database related operation support as a first step. ## Brief change log - created GenericHiveMetastoreCatalog and implemented database related APIs of ReadableWritableCatalog - set up flink-connector-hive module as a result - abstracted common unit tests for GenericInMemoryCatalog and GenericHiveMetastoreCatalog and put them into CatalogTestBase so we can reuse these unit tests ## Verifying this change This change added tests and can be verified as follows: - Reuse previous db related unit tests in GenericInMemoryCatalogTest and move them CatalogTestBase ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no) - The serializers: (no ) - The runtime per-record code paths (performance sensitive): (no) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (no) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature? (yes) - If yes, how is the feature documented? (JavaDocs) Documentation for GenericHiveMetastoreCatalog will be added later when we finish implementing ReadableWritableCatalog APIs
