Subject [jira] Commented: (HIVE-1130) Create argmin and argmax
Date Tue, 31 Aug 2010 20:32:54 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1130?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12904762#action_12904762

John Sichi commented on HIVE-1130:
----------------------------------

Comparing with GenericUDAFMax, I noticed that function uses different inputOI and outputOI,
whereas you use a single xInputOI for both.

      outputOI = ObjectInspectorUtils.getStandardObjectInspector(inputOI,
          ObjectInspectorCopyOption.JAVA);

Maybe you need to follow that pattern?

> With HIVE-1128, users can already do what argmax and argmin does.
> But it will be helpful if we provide these functions explicitly so people from maths/stats
background can use it more easily.
