Peter Varga reassigned HIVE-24233:
----------------------------------
> 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
> Priority: Major
>
> 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;
