Review Comment:
What is the reason not to extend `HplValidationException` with a constructor
which receives `Throwable cause` to wrap the original exception?

Review Comment:
I saw that initializing the `Exec` instance is moved to the constructor of
`Udf`. Could you please elaborate this change?

Review Comment:
Does `info` level is necessary? What happens if the function is called on a
1M record table on each row?
