Jason Dere updated HIVE-13248:
------------------------------
    Attachment: HIVE-13248.4.patch

- Changed DateParser to use Java SimpleDateFormat rather than Joda, which has some date differences. We can look at using Joda and resolving the differences later.
- Fixed a couple of tests.

> Some of the original "date" related functions return string values rather than Date values, because they were created before the Date type existed in Hive. We can try to change these to return Date in the 2.x line.
> Date values should be implicitly convertible to String.
