[jira] [Created] (IMPALA-10997) Refactor code for UDF implementation

Steve Carlin created IMPALA-10997:
-------------------------------------

             Summary: Refactor code for UDF implementation
                 Key: IMPALA-10997
                 URL: https://issues.apache.org/jira/browse/IMPALA-10997
             Project: IMPALA
          Issue Type: Improvement
          Components: Frontend
            Reporter: Steve Carlin


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.
