Teddy Choi commented on HIVE-19306:
-----------------------------------
[~mmccline], [~ewohlstadter]. [^HIVE-19306.3.patch] fixed null handling.
ArrowColumnarBatchSerDe#writeNull is the strangest part. Because Apache Arrow's
UnionListWriter should implement AbstractFieldWriter#writeNull properly and
FieldWriter should have a super method of AbstractFieldWriter#writeNull to
expose it. I used reflection and concrete class check to handle it. I'll fix
FieldWriter interface in Apache Arrow.
