             Summary: Partitions are pruned incorrectly when range-partitioned on a PK prefix
                 Key: KUDU-2173
                 URL: https://issues.apache.org/jira/browse/KUDU-2173
             Project: Kudu
          Issue Type: Bug
          Components: client
    Affects Versions: 1.4.0, 1.3.1, 1.2.0, 1.5.0
            Reporter: Todd Lipcon
            Assignee: Dan Burkert
            Priority: Blocker


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)
