> HIVE-4904 moved GroupBy Optimization to happen before ColumnPruner
> Now, the RewriteGBUsingIndex happens after GroupByOptimization.
> So  setting of bucketGroup flag doesn't happen for Index tables.
> Temporary fix is to update .q.out file.
> Will file a bug to look into moving RewriteGBUsingIndex before GroupByOptimizer.
