Description:
Joining table which contains map of union of 3 types or more is causing
serialization issues.
Given tables:
ag_map_of_uniontype:
# col_name data_type comment
hash string None
custom_fields
mapstring,uniontypebigint,double,string,boolean,int,arrayuniontypebigint,double,string,boolean,int,mapstring,uniontypebigint,double,string,boolean,int
None
ag_simple_join_table:
# col_name data_type comment
hash string None
size int None
Query will throw java.lang.RuntimeException:
{code}
select
i.hash,
i.custom_fields,
b.size
from ag_map_of_uniontype i LEFT OUTER JOIN
ag_simple_join_table b ON (i.hash = b.hash);
{code}
