--------------------------------
Summary: Refactor common partitioning/distribution logic to
BaseAggregateExec
Key: SPARK-32740
URL: https://issues.apache.org/jira/browse/SPARK-32740
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.1.0
Reporter: Cheng Su
For all three different aggregate physical operator: `HashAggregateExec`,
`ObjectHashAggregateExec` and `SortAggregateExec`, they have same
`outputPartitioning` and `requiredChildDistribution` logic. Refactor these same
logic into their super class `BaseAggregateExec` to avoid code duplication and
future bugs (similar to `HashJoin` and `ShuffledJoin`).
