--------------------------------
Description:
I am saving a dask dataframe to parquet with two partition columns using the pyarrow engine. The problem arises in scanning the partition columns. When I scan using the directory path, I get the partition columns in the output dataframe, whereas if I scan using the glob path, I dont get these columns
