   @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 differnt value in its
   parent spark session. Since Spark 3.0, the configurations of a parent `SparkSession`
   have a higher precedence over the parent `SparkContext`
   ```
