AngersZhuuuu opened a new pull request #31598: URL: https://github.com/apache/spark/pull/31598
### What changes were proposed in this pull request? Some user who not so clear about spark when build SparkSession ``` SparkSession.builder().config() ``` In this method user may config `spark.driver.memory` then he will think when submit job, spark driver's memory is change. But when we run this code, JVM has been started, so this configuration won't work at all. And in Spark UI, it will show `spark.driver.memory` as this configuration set by `SparkSession.builder().config()`. This makes user and administer confuse. So we should ignore such as wrong way and logwarn. ### Why are the changes needed? Make usage more clear ### Does this PR introduce _any_ user-facing change?
