I am very much new to the Julia Programming language.
I am trying to load the parquet file using ParquetFiles.load("part-0001-c000-snappy.parquet"). When I run, I got the following error:
**Error displaying ParquetFiles.ParquetFile: ArgumentError: reducing over an empty collection is not allowed**

My requirement is to read multiple parquet files from a directory and convert to DataFrame.
I could able to read the parquet file with another package called Parquet but converting to DataFrames is failing.
Parquet.ParFile("part-0001-c000-snappy.parquet") - able to read successfully.
dataFrame = par |> DataFrames.DataFrame --- Leading to the following error:
**ArgumentError: no default `Tables.columns` implementation for type: ParFile**

in columns at Tables\okt7x\src\fallbacks.jl:239
Please suggest where I am missing as the package documentations are recommending as above.
