Apache Spark reassigned SPARK-28236:
------------------------------------
Assignee: (was: Apache Spark)
> Fix PullOutNondeterministic Analyzer rule to enforce idempotence
> ----------------------------------------------------------------
>
> Key: SPARK-28236
> URL: https://issues.apache.org/jira/browse/SPARK-28236
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Yesheng Ma
> Priority: Major
>
> Previous {{PullOutNonDeterministic}} rule transforms aggregates when the
> aggregating expression has sub-expressions whose {{deterministic}} field is
> set to false. However, this might break {{PullOutNonDeterministic's}}
> idempotence property since the actually aggregation rewriting will only
> transform those with {{NonDeterministic}} trait.
