Subject [jira] [Commented] (HIVE-4142) Remove inferring partition specification behavior
Date Mon, 11 Mar 2013 21:29:14 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4142?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13599336#comment-13599336

Ashutosh Chauhan commented on HIVE-4142:
----------------------------------------

Thinking more about it, I think we should just outright remove support for this. No other
systems supports this. And this is one of the cases where we are adding semantics (allowing
having without a group-by) which will be a deviation from a standard. Further, we are not
getting it for free and have to write and maintain more code for it.

> Remove behavior that:
> - implicitly sets the partition specification of a UDAF
> this interferes with:
> - the user wanting to apply a UDAF on the entire dataset
> - is ambiguous once we support multiple partitions in 1 query.
