the table does not load if the file path has a dot at start

Please check the below code. If I uncomment line six then the table written to disk is loaded as an empty table.

Similar behavior is observed when the directory name starts with `_`. 

This was not the case in earlier versions.

```python

import pyarrow.parquet as pq
import pyarrow as pa
import pathlib
_path = pathlib.Path("abc").resolve()
_path /= "xyz"
_path /= ".lmn" # uncomment this has a 'dot' at start of the folder
_path /= "file_name"
pq.write_to_dataset(
    table=pa.table(

),
    root_path=_path.as_posix()
)
t = pq.read_table(_path)
print(t.to_pandas())

```
