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.
> Hive: DynamicSerDe to support struct inside array/map
> -----------------------------------------------------
>
> Key: HIVE-8
> URL: https://issues.apache.org/jira/browse/HIVE-8
> Project: Hadoop Hive
> Issue Type: Bug
> Reporter: Zheng Shao
>
> 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) >
> );
