> Currently, the functionality for Hive UDFs is such that if the java code throws an exception, the backend logs it as a warning and treats the function as if it returned NULL.
> Sometimes it is desirable to allow the Java function to diagnose an error as fatal to the query. 
> Since this feature would break backward compatibility, the default behavior should be the current behavior.
