   It is not because of the metadata table not bootstrapped, it is because the flink request and check partition small files during write process. When we encounter a new partition, the error throws.
   
   The metadata is designed as a backend of the table files view, while the file-listing based view does not throw for new partition, we should follow that for metadata-based view too.
