After a second thought, isn't it a bug?
```
hive> SELECT `d100.udf100`(`emp`.`name`) FROM `emp`;
USER
```
This clearly violates the SQL semantic: the string inside backticks should
be treated as a string literal. I think we should update the JIRA ticket to
explain this bug, but we don't need to put it in a release notes or migration
guide.
I'll update the ticket.
