Description
reproduce step：
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;
Then ClassCastException occurs.
