Jason Dere commented on HIVE-4844:
----------------------------------
Been going over some of these changes with Gunther Hagleitner, and his input
was that the metastore changes are not necessary for the varchar/decimal type
qualifiers. The type name string is able to hold the whole type description,
and in fact the nested types (struct/map/list) are simply represented as
strings in the metastore. I'll look into reverting the metastore changes in the
patch, and possibly some TypeQualifier-related changes if it makes sense.
