> 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
