    Description

      In its current form, Impala supports Java UDFs that are derived from the UDF.class.  

      The UDF.class is legacy code and Hive now supports implementation off of the GenericUDF.class.

      This Jira is to track the refactoring the current UDF code to allow easier implementation when we eventually support the newer class.  Common code will be put in a base HiveExecutor class and UDF.class specific code will be in a derived class.
