--------------------------------
Summary: ORC SARG evaluation fails with NPE for UDFs or
expressions in predicate condition
Key: HIVE-5986
URL: https://issues.apache.org/jira/browse/HIVE-5986
Project: Hive
Issue Type: Bug
Affects Versions: 0.13.0
Reporter: Prasanth J
Assignee: Prasanth J
{code}select s from orctable where length(substr(s, 1, 2)) <= 2 and s like
'%';{code} kind of queries generate empty child expressions for the operator
(AND in this case). When child expressions are empty evaluate(TruthValue[]
leaves) functions returns null which results in NPE during orc split
elimination or row group elimination.
