> Key: HIVE-22903
> URL: https://issues.apache.org/jira/browse/HIVE-22903
> Project: Hive
> Issue Type: Bug
> Components: UDF, Vectorization
> Affects Versions: 4.0.0
> Reporter: Shubham Chaurasia
> Assignee: Shubham Chaurasia
> Priority: Major
> Labels: pull-request-available
> Attachments: HIVE-22903.01.patch, HIVE-22903.02.patch,
> HIVE-22903.03.patch, HIVE-22903.04.patch, HIVE-22903.patch

> Vectorized row number implementation resets the row number when constant
> expression is passed in partition clause.
> Repro Query
> {code}
> select row_number() over(partition by 1) r1, t from over10k_n8;
> Or
> select row_number() over() r1, t from over10k_n8;
> {code}
> where table over10k_n8 contains more than 1024 records.
> This happens because currently in VectorPTFOperator, we reset evaluators if
> only partition clause is there.
> {code:java}
> // If we are only processing a PARTITION BY, reset our evaluators.
> if (!isPartitionOrderBy) {
> groupBatches.resetEvaluators();
> }
> {code}
> To resolve, we should also check if the entire partition clause is a constant
> expression, if it is so then we should not do
> {{groupBatches.resetEvaluators()}}
