> When using the insert overwrite directory syntax, if the target path is an existing file,
the final operation result is incorrect.
> At present, Spark will not delete the existing files. After the calculation is completed,
one of the result files will be renamed to the result path.
> This is different from hive's behavior. Hive will delete the existing target file.
