[jira] [Commented] (HIVE-6331) HIVE-5279 deprecated UDAF class
without explanation/documentation/alternative
[ https://issues.apache.org/jira/browse/HIVE-6331?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13889137#comment-13889137 ]
Navis commented on HIVE-6331:
-----------------------------
UDAF was deprecated long time before HIVE-5279 and I just added the annotation along with the patch but I should have fixed the javadoc also. Currently, implementing GenericUDAFResolver2 or extending AbstractGenericUDAFResolver is the standard way to implement aggregation function.

> Key: HIVE-6331
> URL: https://issues.apache.org/jira/browse/HIVE-6331
> Project: Hive
> Issue Type: Bug
> Reporter: Lars Francke
> Priority: Minor
>
> HIVE-5279 added a @Deprecated annotation to the {{UDAF}} class. The comment in that class says {quote}UDAF classes are REQUIRED to inherit from this class.{quote}
> One of these two needs to be updated. Either remove the annotation or document why it was deprecated and what to use instead.
> Unfortunately [~navis] did not leave any documentation about his intentions.
> I'm happy to provide a patch once I know the intentions.
