    Description

      Getting a segfault with:

      In [1]: import pyarrow.dataset as ds                                                                                                                                                                               
      
      In [2]: !touch test_empty.txt                                                                                                                                                                                      
      
      In [3]: source_factory = ds.source("test_empty.txt", partitioning=ds.partitioning(field_names=['a', 'b']))                                                                                                         
      
      In [4]: source_factory.inspect()                                                                                                                                                                                   
      Segmentation fault (core dumped)
      

      Didn't yet further investigate what might be the reason (there are several "wrong" things here: it's an empty file, it's not a valid file for the parquet format, the partitioning does not match the files, etc)
