There is a hive unit test called `udf_div.q` and it is very simple. The
content is...
```
DESCRIBE FUNCTION div;
DESCRIBE FUNCTION EXTENDED div;
SELECT 3 DIV 2 FROM SRC LIMIT 1;
```
I think we can ignore it. But, to keep track how many hive unit tests we
can pass, maybe it is better to record it in `HiveCompatibilitySuite`?
