[jira] [Created] (SPARK-37746) log4j2-defaults.properties is not working since log4j 2 is always initialized by default

Chia-Ping Tsai created SPARK-37746:
--------------------------------------

             Summary: log4j2-defaults.properties is not working since log4j 2 is always initialized by default
                 Key: SPARK-37746
                 URL: https://issues.apache.org/jira/browse/SPARK-37746
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 3.3.0
            Reporter: Chia-Ping Tsai


the code used to check initialization is shown below.

      val log4j2Initialized = !LogManager.getRootLogger
        .asInstanceOf[org.apache.logging.log4j.core.Logger].getAppenders.isEmpty

That works for log4j. However, log4j2 provides a default configuration so there is always a appender (ConsoleAppender) with error level.
