-----------------------------------
Summary: MapJoin operator shoud not be vectorized when Projections
contains complex types
Key: HIVE-25456
URL: https://issues.apache.org/jira/browse/HIVE-25456
Project: Hive
Issue Type: Bug
Components: Vectorization
Affects Versions: 3.1.0
Reporter: gaozhan ding
reproduce step：
{code:java}
create table map_test1(str string,str_map map<string, string>);
create table map_test2(str string,str_map map<string, string>);
insert into map_test1
values('xxx',map('key','value')),('yyy',map('key','value'));
insert into map_test2
values('xxx',map('key','value')),('yyy',map('key','value'));
set hive.vectorized.execution.enabled=true;
set hive.auto.convert.join=true;
select a.str_map from map_test1 a join map_test2 b on a.str=b.str;{code}
Then ClassCastException occurs.
