Pengcheng Xiong commented on HIVE-11445:
----------------------------------------
groupby2_map_multi_distinct does not work on return path. In the old return
path, there is a function called "getDistinctColIndicesForReduceSink" but now
there is no correspondent in the return path.
> CBO: Calcite Operator To Hive Operator (Calcite Return Path) : groupby
> distinct does not work
