dilipbiswal edited a comment on issue #24279: [SPARK-27253][SQL][FOLLOW-UP] Add a note about parent-session configuration priority in migration guide URL: https://github.com/apache/spark/pull/24279#issuecomment-479699645 @HyukjinKwon A slightly different version for your perusal. ``` In Spark version 2.4, when a spark session is created via `cloneSession()`, the newly created spark session inherits its configuration from its parent `SparkContext` even though the same configuration may exist with a different value in its parent spark session. Since Spark 3.0, the configurations of a parent `SparkSession` have a higher precedence over the parent `SparkContext` ```
