arina-ielchiieva commented on pull request #1839: DRILL-4517: Support reading
empty Parquet files
URL: https://github.com/apache/drill/pull/1839
1. Modified flat and complex parquet readers to output schema only when
requested number of records to read is 0. In this case readers are not
initialized to improve performance.
2. Allowed reading requested number of rows instead of all rows in the row
group (DRILL-6528).
3. Fixed issue with nulls number determination in the row group (fixed
IsPredicate#isAllNulls method).
4. Allowed reading empty parquet files via adding empty / fake row group.
5. General refactoring and unit tests.

I've also attached a Parquet file containing no rows (generated from PyArrow)
in case it helps:

-
No, this issue is not fixed yet. In DRILL-2223 we fixed CTAS to no longer
create empty parquet files. We still need to fix Drill, if possible, to
properly handle such files.
Can you share this particular parquet file ? thanks
