> HIVE-13555 adds support for nullif. I'm encountering issues with nullif on master (3.0.0-SNAPSHOT rdac3786d86462e4d08d62d23115e6b7a3e534f5d)
> Cluster side jobs work fine but client side don't.
> Consider these two tables:
> e011_02:
> Columns c1 = float, c2 = double
> 1.0 1.0
> 1.5 1.5
> 2.0 2.0
> test:
> Columns c1 = int, c2 = int
> Data:
> 1 1
> 2 2
> And this query:
> select nullif(c1, c2) from e011_02;
> With e011_02 I get:
> {code}
