[jira] [Created] (HIVE-20381) Vectorization: Reduce dedup of GroupBy + PTF turns off vectorization

 Summary: Vectorization: Reduce dedup of GroupBy + PTF turns off 
vectorization
 Key: HIVE-20381
 URL: https://issues.apache.org/jira/browse/HIVE-20381
 Project: Hive
  Issue Type: Bug
  Components: Vectorization
Affects Versions: 3.1.0, 4.0.0
Reporter: Gopal V


One of the PTF Reducers in Query51 is not vectorized because there's a reduce 
deduplication which combines a group-by and a windowing shuffle.

{code}
| Reducer 8  |
| Execution mode: llap   |
| Reduce Vectorization:  |
| enabled: true  |
| enableConditionsMet: hive.vectorized.execution.reduce.enabled 
IS true, hive.execution.engine tez IN [tez, spark] IS true |
| notVectorizedReason: PTF operator: Only PTF directly under 
reduce-shuffle is supported |
| vectorized: false   
{code}

It vectorizes all PTF vertices (after HIVE-20367), with {{ set 
hive.optimize.reducededuplication=false;}}
