Subject [jira] Commented: (HIVE-555) create temporary function support not only udf, but also udaf, genericudf, etc.
Date Thu, 09 Jul 2009 16:54:14 GMT

    [ https://issues.apache.org/jira/browse/HIVE-555?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12729322#action_12729322

Namit Jain commented on HIVE-555:

The tests fail right now.

In the new test create_udaf.q, you need to drop the temporary function test_max.

But a new bug got exposed, if there are two functions pointing to the same class (max and
test_max) in this case, the resolver might point to one function even though
another one is referenced. I will test it out separately, and file a jira for that if needed.

Anyway, as this patch stands, all tests after create_udaf.q which reference max, get an error
because explain plan shows test_max instead.
