    Thank you for your work! 
    
    Maybe the last question.
    
    ```
    **2. CREATE TABLE ...PARTITIONED BY ... LOCATION path AS SELECT ...**
    a) path exists
          hive(external) -> not support
              spark(hive with HiveExternalCatalog) -> ok
          spark(parquet with HiveExternalCatalog) -> throw exception(path 
already exists)
              spark(parquet with InMemoryCatalog) -> throw exception(path 
already exists)
    ```
    
    In the above case, you used `path exists`. I assumed this is the existence 
of the table directory. Are these behaviors still the same when the specific 
partition directory exists?
