----------------------------------
Summary: 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
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.
