[jira] [Created] (HIVE-2475) Allow UDAFs to short-circuit

Allow UDAFs to short-circuit
----------------------------

                 Key: HIVE-2475
                 URL: https://issues.apache.org/jira/browse/HIVE-2475
             Project: Hive
          Issue Type: Improvement
            Reporter: Adam Kramer
            Priority: Minor


Imagine a udaf called ALL, which returns true when ALL of the entries in the column are true. Then, this UDAF can return false for the group as soon as any item seen is false. The Hive UDF framework should provide a manner by which a UDAF can "short-circuit" further evaluation and thus systematically ignore the rest of the rows that will be pushed in.
