[jira] [Commented] (HIVE-2532) Evaluation of
non-deterministic/stateful UDFs should not be skipped even if constant oi
is returned.
[ https://issues.apache.org/jira/browse/HIVE-2532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13138595#comment-13138595 ]
Jonathan Chang commented on HIVE-2532:
--------------------------------------
I have a patch but don't have a good testcase yet. This might be a good time to add a side-effecting UDF. Any suggestions?
