> Project: Hive
> Issue Type: Improvement
> Reporter: Yin Huai
> Priority: Minor
>
> When map-side-aggregation is disabled (hive.map.aggr=false), constant values
> in aggregation parameters are attached to every map output row. For example,
> in test case 'count.q'
> (https://github.com/apache/hive/blob/trunk/ql/src/test/results/clientpositive/count.q.out).
> For count(1), if hive.map.aggr=false, '1' will be attached to every output
> row of ReduceSinkOperator.
