>
> After HIVE-2792, the substr function produces a
> StringIndexOutOfBoundsException when called on a string containing UTF-8
> characters without the length argument being present.
> E.g.
> select substr(str, 1) from table1;
> now fails with that exception if str contains a UTF-8 character for any row
> in the table.
