Teruyoshi Zenmyo commented on HIVE-3508:
----------------------------------------
Is anyone working on this? Otherwise, I'll try the following.
1. add a new operator which multiplexes records for each grouping id
2. insert the new operator before ReduceSinkOperators
Please let me know if anything wrong on this.
> create cube and rollup operators in hive without mapside aggregation
