Pete Wyckoff commented on HIVE-8:
---------------------------------

DynamicSerDe now fully supports nested structures and was committed as part of one of those
initial megacommits.

Need support from CLI and metastore for this now.

> We should allow users to create types and use those types in dynamic serde.
> In this way we can support:
> CREATE TYPE friend_information (
>   friend_id int,
>   friend_name string
> );
> CREATE TABLE user_information {
>   user_id int,
>   user_name string,
>   friends array<friend_information>
> );
> Or support in-place declaration:
> CREATE TABLE user_information {
>   user_id int,
>   user_name string,
>   friends array<TYPE user_information(friend_id int,  friend_name string) >
> );
