Teddy Choi updated HIVE-5761:
-----------------------------

    Attachment: HIVE-5761.1.patch

I attached my draft implementation and tests. A date vector is putted on the static WeakHashMap instance on DateUtil, so its type can be checked later.

However, I think vectors needs type data on implementation to support UDFs with various input types.

> Add support to allow queries referencing DATE columns and expression results to run efficiently in vectorized mode. This should re-use the code for the the integer/timestamp types to the extent possible and beneficial. Include unit tests and end-to-end tests. Consider re-using or extending existing end-to-end tests for vectorized integer and/or timestamp operations.
