   @cloud-fan 
   At the beginning, I also would like to achieve it by changing the config of `SparkContext`, but changing the config of `SparkContext` cannot overwrite the configuration already contained in [initialSessionOptions](https://github.com/apache/spark/blob/071feabbd4325504332679dfa620bc5ee4359370/sql/core/src/main/scala/org/apache/spark/sql/SparkSession.scala#L257).
   
   The advantage of the UI feature over the REST API is that it can display configurations that have been overridden.
   
   @yaooqinn Spark UI is not only for monitoring, it can also kill jobs.
