----------------------------------
Summary: except subquery throws nullpointer with cbo disabled
Key: HIVE-24233
URL: https://issues.apache.org/jira/browse/HIVE-24233
Project: Hive
Issue Type: Bug
Reporter: Peter Varga
Assignee: Peter Varga
Except and intersect was only implemented with Calcite in HIVE-12764. If cbo is
disabled it would just throw a nullpointer exception. We should at least throw
a SemanticException stating this is not supported.
Repro:
set hive.cbo.enable=false;
create table test(id int);
insert into table test values(1);
select id from test except select id from test;
