+1 Looks good to me. I ran convert_decimal64_to_decimal.q test with
HIVE-20315.08.patch patch on my machine. It had few differences. Other things
look good.

+1 Looks good to me. I ran convert_decimal64_to_decimal.q test with
HIVE-20315.08.patch patch on my machine. It had just one difference as
following. Other things look good.
LINE 184: bigTableKeyExpressions: ConvertDecimal64ToDecimal(col
3:decimal(9,2)/DECIMAL_64) -> 20:decimal(9,2)
Should be: bigTableKeyExpressions: ConvertDecimal64ToDecimal(col
3:decimal(9,2)/DECIMAL_64) -> 21:decimal(9,2)

> Generate multi-byte Unicode characters in addition to regular single byte
> characters for random data.
> Don't CAST from STRING/VARCHAR/CHAR TO STRING since all are stored in
> vectorization without padding.
> Fix vectorized BETWEEN expression work to avoid unnecessary CAST of DECIMAL
> constants.
> Fix NULL / Wrong Results issues in VectorElt.
> Change performance Q files to generate non-user EXPLAIN with VECTORIZATION
> display so unnecesary CAST / DECIMAL_64 conversions are visible.
> Add test for vectorized STRUCT field reference.
