>             Project: Kudu
>          Issue Type: Bug
>          Components: client
>    Affects Versions: 1.2.0, 1.3.1, 1.4.0, 1.5.0

> Given a schema:
> {code}
> Schema [
>   0:a[int8 NOT NULL],
>   1:b[int8 NOT NULL]
> ]
> PRIMARY KEY (a,b)
> {code}
> and a partition:
> {code}
> RANGE (a) PARTITION VALUES >= 10
> {code}
> ... the partition pruner incorrectly handles the following scan spec:
> {code}
>  `a` < 11 AND `b` < 11
> {code}
> ... and prunes the partition despite the possibility of it having a row like (10, 1)
