Subject [jira] [Commented] (HIVE-2592) ConstantOI doesn't always propagate to UDAF
Date Mon, 28 Nov 2011 22:49:40 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2592?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13158892#comment-13158892

Phabricator commented on HIVE-2592:
-----------------------------------

jsichi has requested changes to the revision "HIVE-2592 [jira] ConstantOI doesn't always propagate
to UDAF".

  I got many failures from running ant test on this one.  I think at this point it would make
sense for you to set up a dev box so you can run through ant test yourself.  (Marek has the
parallel test stuff ready to try too.)

> Depending on the query plan, a UDAF may not actually get a constant OI.  E.g.,
> set hive.map.aggr=false;
> SELECT percentile_approx(cast(substr(src.value,5) AS double), 0.5) FROM src;
