> The to_date method behaves differently based off the 'data type' of null passed in.
> hive> select to_date(null);                   
> FAILED: SemanticException [Error 10014]: Line 1:7 Wrong arguments 'TOK_NULL': TO_DATE()
only takes STRING/TIMESTAMP/DATEWRITABLE types, got VOID
> hive> select to_date(cast(null as timestamp));
> OK
> NULL
> Time taken: 0.031 seconds, Fetched: 1 row(s)
> This appears to be a regression introduced in HIVE-5731.  The previous version of to_date
would not check the type:
