dongjoon-hyun opened a new pull request #25276: [SPARK-28545][SQL] Add the hash map size to the directional log of Ob jectAggregationIterator URL: https://github.com/apache/spark/pull/25276 ## What changes were proposed in this pull request? `ObjectAggregationIterator` shows a directional info message to increase `spark.sql.objectHashAggregate.sortBased.fallbackThreshold` when the size of the in-memory hash map grows too large and it falls back to sort-based aggregation. However, we don't know how much we need to increase. This issue add the size of the current in-memory hash map size to the log message. ## How was this patch tested? Manual.
