> HIVE-16091 added support for subqueries in SELECT clause but restricted subqueries to
top level expressions (more detail is at [LINK | https://cwiki.apache.org/confluence/display/Hive/Subqueries+in+SELECT])
> This restriction will be relaxed to allow subqueries in all kind of expression except
UDAF (including UDAs and UDTFs).
