   @JoshuaZhuCN let me clarify: when it comes to delete the whole table, we support 3 syntaxes
   
   - TRUNCATE TABLE: delete all records via file system; table retained in metastore
   - DROP TABLE: delete no record; table removed from metastore
   - DROP TABLE PURGE: delete all records via file system; table removed from metastore
   
   So in your case where you expect data deleted from the storage, you should use 
   
   ```sql
   DROP TABLE IF EXISTS `default`.`spark_hudi_test_ddl` PURGE;
   ```
   
   If you use `DROP TABLE` (without purge) and you want to recreate the table again, your CREATE TABLE statement should just be
   
   ```sql
   CREATE TABLE IF NOT EXISTS `default`.`spark_hudi_test_ddl` USING HUDI
   LOCATION 'hdfs://localhost:9000/hudi/test/spark_hudi_test_ddl';
   ```
