Chao Sun commented on HIVE-15233:
---------------------------------
One problem is uuid() generates random ids, so the test result will be
different every time. Here I just count the distinct values from the select and
show that it indeed generate different uuids for different rows.
> UDF UUID() should be non-deterministic
