Reynold Xin updated SPARK-17720:
--------------------------------
Description:
Spark SQL has two kinds of configuration parameters: dynamic configs and static
configs. Dynamic configs can be modified after Spark SQL is launched (after
SparkSession is setup), whereas static configs are immutable once the service
starts.
It would be useful to have this separation and tell users if the user tries to
set a static config after the service starts.
