-------------------------------
Summary: Show result expressions in AggregateExec
Key: SPARK-42831
URL: https://issues.apache.org/jira/browse/SPARK-42831
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.4.0
Reporter: Wan Kun
If the result expressions in AggregateExec is non-empty, we should show them.
Or we will be confused due to some important expressions did not showed in DAG.
For example, the plan of query SELECT sum(p) from values(cast(23.4 as
decimal(7,2))) t(p) was not correct because the result expression
MakeDecimal(sum(UnscaledValue(p#0))#1L,17,2) AS sum(p)#2 was now showing
