[jira] [Created] (SPARK-18870) Distinct aggregates give incorrect answers on streaming dataframes

Tathagata Das created SPARK-18870:
-------------------------------------

             Summary: Distinct aggregates give incorrect answers on streaming dataframes
                 Key: SPARK-18870
                 URL: https://issues.apache.org/jira/browse/SPARK-18870
             Project: Spark
          Issue Type: Bug
            Reporter: Tathagata Das
            Assignee: Tathagata Das
            Priority: Blocker


Unsupported operations checking dont check whether AggregationExpression have isDistinct=true. So `streamingDf.groupBy().agg(countDistinct("key")) ` gives incorrect results.
