> Project: Hive
> Issue Type: Sub-task

> Priority: Blocker
> Labels: hive-4.0.0-must

> TPC-DS query 97 returns wrong results when hive.auto.convert.join and
> hive.vectorized.execution.enabled are set to true.
>
> Result of query 97 on 1TB text dataset:
> CommonMergeJoinOperator(hive.auto.convert.join=false): 534151529,
> 284185{*}746{*}, 84163
> MapJoinOperator(hive.auto.convert.join=true,
> hive.vectorized.execution.enabled=false): 534151529, 284185{*}746{*}, 84163
> VectorMapJoinOperator(hive.auto.convert.join=true,
> hive.vectorized.execution.enabled=true): 534151529, 284185{*}388{*}, 84163
>
> Also I observed that VectorizedMapJoin returns different results for 100GB
> dataset when I run query 97 twice, but I could not reproduce it since then.
