> 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;
