## What changes were proposed in this pull request? This PR adds support for Hive UDFs that return fully typed java Lists or Maps, for example `List<String>` or `Map<String, Integer>`. It is also allowed to nest these structures, for example `Map<String, List<Integer>>`. Raw collections or collections using wildcards are still not supported, and cannot be supported due to the lack of type information. ## How was this patch tested? Modified existing tests in `HiveUDFSuite`, and I have added test cases for raw collection and collection using wildcards.
