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

             Summary: Add more information in ERROR log while SparkConf is modified when spark.sql.legacy.setCommandRejectsSparkCoreConfs is set
                 Key: SPARK-36643
                 URL: https://issues.apache.org/jira/browse/SPARK-36643
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.1.2
            Reporter: Senthil Kumar


Right now, by default sql.legacy.setCommandRejectsSparkCoreConfs is set as true in Spark 3.* versions int order to avoid changing Spark Confs. But from the error message we get confused if we can not modify/change Spark conf in Spark 3.* or not.

Current Error Message :
{code:java}
Exception in thread "main" org.apache.spark.sql.AnalysisException: Cannot modify the value of a Spark config: spark.driver.host
 at org.apache.spark.sql.RuntimeConfig.requireNonStaticConf(RuntimeConfig.scala:156)
 at org.apache.spark.sql.RuntimeConfig.set(RuntimeConfig.scala:40){code}
 

So adding little more information( how to modify Spark Conf), in ERROR log while SparkConf is modified when spark.sql.legacy.setCommandRejectsSparkCoreConfs is 'true', will be helpful to avoid confusions.
