> This simple Hive query would generate wrong result:
> select a.key, b.k2, b.k3
> from src a
> join (
>   select key, 
>          min(key) as k,
>          min(key)+1 as k1,
>          min(key)+2 as k2,
>          min(key)+3 as k3
>   from src
>   group by key
> ) b
> on a.key=b.key and b.k1 < 5;
> 0       3.0     1.0
> 0       3.0     1.0
> 0       3.0     1.0
> 2       5.0     3.0
> The right result is:
> 0	2.0	3.0
> 0	2.0	3.0
> 0	2.0	3.0
> 2	4.0	5.0
