Antoine Pitrou created ARROW-17633:
--------------------------------------
Summary: [Python][CI] test_write_dataset_max_rows_per_file is flaky
Key: ARROW-17633
URL: https://issues.apache.org/jira/browse/ARROW-17633
Project: Apache Arrow
Issue Type: Bug
Components: Continuous Integration, Python
Reporter: Antoine Pitrou
I am starting to see intermittent but frequent CI failures in
{{test_write_dataset_max_rows_per_file}}.
Is {{write_dataset}} supposed to create the base directory?
