> 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.
