Harish Butani created HIVE-4358:
-----------------------------------
Summary: Check for Map side processing in PTFOp is no longer valid
Key: HIVE-4358
URL: https://issues.apache.org/jira/browse/HIVE-4358
Project: Hive
Issue Type: Bug
Components: PTF-Windowing
Reporter: Harish Butani
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
