peter-toth opened a new pull request, #39887: URL: https://github.com/apache/spark/pull/39887
### What changes were proposed in this pull request? Unfortunately https://github.com/apache/spark/pull/32298 introduced a regression from Spark 3.2 to 3.3 as after that change a merged subquery can contain multiple distict type aggregates. Those aggregates need to be rewritten by the `RewriteDistinctAggregates` rule to get the correct results. This PR fixed that. ### Why are the changes needed? The following query: ``` SELECT (SELECT count(distinct c1) FROM t1), (SELECT count(distinct c2) FROM t1) ``` currently fails with: ``` java.lang.IllegalStateException: You hit a query analyzer bug. Please report your query to Spark user mailing list. at org.apache.spark.sql.execution.SparkStrategies$Aggregation$.apply(SparkStrategies.scala:538) ``` but works again after this PR. ### Does this PR introduce _any_ user-facing change? Yes, the above query works again. ### How was this patch tested? Added new UT. -- This is an automated message from the Apache Git Service.
