[jira] Created: (HIVE-359) Short-circuiting expression evaluation

Short-circuiting expression evaluation
--------------------------------------

                 Key: HIVE-359
                 URL: https://issues.apache.org/jira/browse/HIVE-359
             Project: Hadoop Hive
          Issue Type: Improvement
            Reporter: Zheng Shao


We don't need to evaluate some sub-expressions for AND, OR, CASE, and IF.
We should support this kind of expression operators natively so we can change the evaluation order and do short-circuiting.
