> Project: Hive
> Issue Type: Improvement
> Components: Query Processor
> Affects Versions: 0.10.0, 0.11.0
> Reporter: Xuefu Zhang

> Priority: Minor
> Fix For: 0.12.0

>
> 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.
