---------------------------------
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.
