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


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.
