-------------------------------------

             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.
