########## File path: flink-connectors/flink-connector-hive/src/main/java/org/apache/flink/table/catalog/hive/HiveCatalogBase.java ########## @@ -89,6 +101,34 @@ private static IMetaStoreClient getMetastoreClient(HiveConf hiveConf) { } } + // ------ APIs ------ + + /** + * Validate input base table. + * + * @param catalogBaseTable the base table to be validated + * @throws IllegalArgumentException thrown if the input base table is invalid. + */ + protected abstract void validateCatalogBaseTable(CatalogBaseTable catalogBaseTable) Review comment: Make sense. Though IllegalArgumentException can be thrown when any part of the input table is invalid, a better signature may just be throwing CatalogException to conform with that of other existing catalog APIs, since we've defined CatalogException's use case as "in case of any runtime exception". I don't think returning boolean is a good signature as the check can be fairly complicated and the caller won't know which part is invalid. Returning boolean would be a good option for a single criteria check like "bool isTable()". ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
