Terry Kim 59db1f617a [SPARK-29609][SQL] DataSourceV2: Support DROP NAMESPACE ... ### What changes were proposed in this pull request? This PR adds `DROP NAMESPACE` support for V2 catalogs. ### Why are the changes needed? Currently, you cannot drop namespaces for v2 catalogs. ### Does this PR introduce any user-facing change? The user can now perform the following: ```SQL CREATE NAMESPACE mycatalog.ns DROP NAMESPACE mycatalog.ns SHOW NAMESPACES IN mycatalog # Will show no namespaces ``` to drop a namespace `ns` inside `mycatalog` V2 catalog. ### How was this patch tested? Added unit tests. Closes #26262 from imback82/drop_namespace. Authored-by: Terry Kim <yuminkim@gmail.com> Signed-off-by: Dongjoon Hyun <dhyun@apple.com>		2019-10-28 15:00:22 -07:00
