-------------------------------------
Summary: TPCDS queries q15, q19, q23a, q45, q58 are failing when
hive.vectorized.execution.mapjoin.native.fast.hashtable.enabled is set to true
Key: HIVE-28735
URL: https://issues.apache.org/jira/browse/HIVE-28735
Project: Hive
Issue Type: Bug
Components: Vectorization
Affects Versions: 4.0.1, 4.0.0
Reporter: Paramvir Singh
TPCDS queries q15, q19, q23a, q45, q58 are failing when
hive.vectorized.execution.mapjoin.native.fast.hashtable.enabled is set to
true.
Setup should include atleast 2 node cluster. It's passing when the cluster has
only 1 node.
The wrong result is also random(on each run I get different random wrong
values).
Small repro query on TPCDS dataset
{code:java}
select ca_zip, count(*)
from catalog_sales_small, customer_small, customer_address_small
where cs_bill_customer_sk = c_customer_sk
and c_current_addr_sk = ca_address_sk
group by ca_zip
order by ca_zip
limit 100;
{code}
If we set the following properties, we get correct results
{code:java}
set hive.vectorized.execution.enabled=false; - Correct results
{code}
OR
{code:java}
set hive.auto.convert.join=false; - Correct results
{code}
