> Currently, partition spec containing same column for partition-by and order-by makes
duplicated key column for RS. For example, 
> {noformat}
> explain
> select p_mfgr, p_name, p_size, 
> rank() over (partition by p_mfgr order by p_name) as r, 
> dense_rank() over (partition by p_mfgr order by p_name) as dr, 
> sum(p_retailprice) over (partition by p_mfgr order by p_name rows between unbounded preceding
and current row)  as s1
> from noop(on noopwithmap(on noop(on part 
> partition by p_mfgr 
> order by p_mfgr, p_name
> )))
> {noformat}
> "partition by p_mfgr order by p_mfgr, p_name" makes duplicated key columns like below
> {noformat}
> Reduce Output Operator
>     key expressions: p_mfgr (type: string), p_mfgr (type: string), p_name (type: string)
>     sort order: +++
>     Map-reduce partition columns: p_mfgr (type: string)
>     value expressions: p_size (type: int), p_retailprice (type: double)
> {noformat}
