Quanlong Huang updated IMPALA-10997:
------------------------------------
Fix Version/s: Impala 4.1.0
> 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
> Assignee: Steve Carlin
> Priority: Major
> Fix For: Impala 4.1.0
>
>
> 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.
