             Summary: Partition pruning / scan optimization fails with IS NOT 
NULL predicate on PK column
                 Key: KUDU-1652
                 URL: https://issues.apache.org/jira/browse/KUDU-1652
             Project: Kudu
          Issue Type: Sub-task
    Affects Versions: 1.0.0
            Reporter: Dan Burkert
            Assignee: Dan Burkert
            Priority: Blocker


Both the Java client and C++ client/server currently have a bug where 
attempting a scan with an {{IS NOT NULL}} predicate on a primary key column can 
through an exception (Java), or crash the C++ client or server.  This is a rare 
situation currently since {{IS NOT NULL}} is not publicly accessible, so it has 
to come from a simplified predicate like {{my_int8_column <= 127}}.  The fix is 
straightforward: stop encoding the lower/upper bound keys when an {{IS NOT 
NULL}} predicate is encountered.
