-------------------------------------
Summary: Add the hash map size to the directional log of ObjectAggregationIterator
Key: SPARK-28545
URL: https://issues.apache.org/jira/browse/SPARK-28545
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.0.0
Reporter: Dongjoon Hyun
`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.
