> 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
