             Summary: [Python][C++] Order of files are not respected using the new pyarrow.dataset
                 Key: ARROW-9063
                 URL: https://issues.apache.org/jira/browse/ARROW-9063
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++, Python
    Affects Versions: 0.17.1
         Environment: ubuntu-18.04
            Reporter: William Liu


Say we have multiple parquet files under the same folder (a.parquet, b.parquet, c.parquet). If I pass a list of file paths into either of the two statements below
{code:java}
ds = pq.ParquetDataset(fps, use_legacy_dataset=False)
ds = pyarrow.dataset(fps){code}
Then rows of the resulting table will have:

aaaa...bbbb...aaa...bbbb...aaa...ccc..bbb...cccc
