>             Project: Hive
>          Issue Type: Bug
>          Components: Physical Optimizer
>    Affects Versions: 2.2.0
>            Reporter: Jesus Camacho Rodriguez

> The goal is to extend the work started in HIVE-14002.
> For instance, given the following query:
> {code:sql}
> explain
> select key, value, count(key + 1) as agg1 from src 
> group by key, value
> order by key, value, agg1 limit 20;
> {code}
> We generate the following physical plan:
> {{TS1 - GBY2 - RS3 - GBY4 - RS5 - SEL6 - LIM7 - FS8}}
> We can push the limit to RS3 operator, as we will generate records for the _top N_ keys,
and thus, GBY4 will produce the _top N_ results. However, currently we do not do it.
