The ParquetDatasetFactory now stores the paths in a list alongside the path-to-id map so that it can create the dataset with a properly ordered set of paths. I added a test to test_dataset.py to confirm this. Note: While this does fix the issue, writing a dataset is still non-deterministic. This is probably inevitable if partitioning is present. Grouping rows by a partition will destroy any ordering that previously existed. Furthermore, since the current implementation writes with multiple threads, there is no predictable order in which output files are created. -- This is an automated message from the Apache Git Service.
