Description

Steps to reproduce:

CREATE TABLE test_orc (a INT, b MAP<INT, STRING>) STORED AS ORC;
INSERT OVERWRITE TABLE test_orc SELECT 1, MAP(1, "one", 2, "two") FROM src LIMIT 1;
CREATE TABLE test(key INT) ;
INSERT OVERWRITE TABLE test SELECT 1 FROM src LIMIT 1;

set hive.vectorized.execution.enabled=true;
set hive.auto.convert.join=false;

select l.key from test l left outer join test_orc r on (l.key= r.a) where r.a is not null;
