                 URL: https://issues.apache.org/jira/browse/HIVE-619
             Project: Hadoop Hive
          Issue Type: Bug
          Components: Query Processor
            Reporter: Namit Jain


While creating a (temporary) function, if the underlying class does not exist - 
the current error message is very cryptic.
It should be  something like "Class xxxx not found" or "Class xxxx does not 
implement UDF, GenericUDF, or UDAF"
