luoyuxia updated HIVE-5737:
---------------------------
Description:
# In UDTF, column names can be useful sometimes. For example, complex function
with many optional parameters something like,
xml_explode('\t' as field, '\n' as line, '=' as mapkey, ':' as items, input)
Without column name, it's not easy to discern each parameter is for what.
