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.
