Senthil Kumar created SPARK-36643:
-------------------------------------
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.
