Matt McCline commented on HIVE-19306:
-------------------------------------
[~teddy.choi] The part that I see NULL issues (so far) is in the
ArrowColumnarBatchSerDe.write handling of selectedInUse. However, my
impression is you are only writing the batch you fill from row-mode and that
doesn't have selected rows.
