Dustin Zubke updated ARROW-15286: --------------------------------- Description: Whenever I try calling the `pyarrow.dataset.FileSystemDataset.take` method, I get a segmentation fault. I first encountered this using a proprietary dataset and recreated it with the UC Davis data below. I can successfully run the pyarrow.dataset.FileSystemDataset.to_batches method but not the take() method. Steps to recreate: {code:java} !wget https://anson.ucdavis.edu/~clarkf/pems_parquet.zip !unzip -q pems_parquet.zip import pyarrow.dataset as ds file_path= "./pems_sorted/station=402264/part-r-00151-ddaee723-f3f6-4f25-a34b-3312172aa6d7.snappy.parquet" dataset = ds.dataset(file_path) dataset.take(1) 80874 segmentation fault {code} Creating a dataset from a directory as below also results in a segfault. {code:java} dir_path = "./pems_sorted/station=402264" dataset = ds.dataset(dir_path) dataset.take(1) {code} Environments tried: * Ubuntu 18.04, Python 3.8.6 * macOS 11.6.2, Python 3.7.5 was: Whenever I try calling the `pyarrow.dataset.FileSystemDataset.take` method, I get a segmentation fault.
