HCatalog integration has the following limitations:
- HCatalog integration queries and describe commands do not support
complex types; only primitive types are supported. Use PXF external tables to
query complex types in Hive. (See [Complex Types Example](#complex_dt_example).)
-- Even for primitive types, HCatalog metadata descriptions produced by
`\d` and` \d+` are converted to HAWQ types. For example, the Hive type
`tinyint` is converted to HAWQ type `int2`. (See [Data Type
Mapping](#hive_primdatatypes).)

In this case more accurate is to say that \d show's Hawq's interpretation
of underlying Hive's datatypes, and \d+ shows both interpreted and original
types.
