Andrew Ray 37cff1b1a7 [SPARK-11275][SQL] Incorrect results when using rollup/cube ... Fixes bug with grouping sets (including cube/rollup) where aggregates that included grouping expressions would return the wrong (null) result. Also simplifies the analyzer rule a bit and leaves column pruning to the optimizer. Added multiple unit tests to DataFrameAggregateSuite and verified it passes hive compatibility suite: ``` build/sbt -Phive -Dspark.hive.whitelist='groupby.*_grouping.*' 'test-only org.apache.spark.sql.hive.execution.HiveCompatibilitySuite' ``` This is an alternative to pr https://github.com/apache/spark/pull/9419 but I think its better as it simplifies the analyzer rule instead of adding another special case to it.
