> With the changes for ReduceSinkDedup it is no longer true that a non Map-side PTF Operator is preceded by an ExtractOp. For e.g. following query can produce the issue:
> {noformat}
> create view IF NOT EXISTS mfgr_price_view as 
> select p_mfgr, p_brand, 
> sum(p_retailprice) as s 
> from part 
> group by p_mfgr, p_brand;
>         
> select p_mfgr, p_brand, s, 
> sum(s) over w1  as s1
> from mfgr_price_view 
> window w1 as (distribute by p_mfgr sort by p_brand rows between 2 preceding and current row);
> {noformat}
> Fix is to add an explicit flag to PTFDesc
