> When Hive provides a list of candidate functions in case of UDFArgumentException such
as for the following query:
> {code}
> create table tbl (a binary);
> select cast (a as tinyint) from tbl limit 1;
> {code}
> the list is not sorted, so the output is not deterministic. Also, we have many test cases
depending on the ordering. Thus, it's good to sort the list before emitting it.
> This should fixes quite a few test case failures when Hive runs in JDK7.
