[jira] [Created] (SPARK-12578) Parser should not silently ignore the distinct keyword used in an aggregate function when OVER clause is used

Reynold Xin created SPARK-12578:
-----------------------------------

             Summary: Parser should not silently ignore the distinct keyword used in an aggregate function when OVER clause is used
                 Key: SPARK-12578
                 URL: https://issues.apache.org/jira/browse/SPARK-12578
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
            Reporter: Reynold Xin


Right now, when an aggregate function is used as window function and DISTINCT is used, Hive's parser silently drop the DISTINCT keyword. It is fine to not support DISTINCT aggregation in window function. But, it is not good to silently drop the keyword.
