-------------------------------------

             Summary: Reverse not dealing with unicode grapheme clusters correctly
                 Key: HIVE-24620
                 URL: https://issues.apache.org/jira/browse/HIVE-24620
             Project: Hive
          Issue Type: Bug
            Reporter: Quanlong Huang


Reverse() deal with unicode code points instead of grapheme clusters:
{code:java}
hive> select 'abc\u0303def', reverse('abc\u0303def');
OK
abc̃def fed̃cba{code}
Note that "~" should on top of "c" in the result.
