------------------------------------
Summary: NoClassDefFoundError for
org.slf4j.impl.StaticLoggerBinder in org.apache.spark.Logging#isLog4j12 when
using SLF4J/Logback 2.x
Key: SPARK-36316
URL: https://issues.apache.org/jira/browse/SPARK-36316
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 3.1.2
Reporter: Ian Springer
When using SLF4J 2.x, I hit the following exception:
java.lang.NoClassDefFoundError: org/slf4j/impl/StaticLoggerBinder
Caused by: java.lang.ClassNotFoundException: org.slf4j.impl.StaticLoggerBinder
This is because org.slf4j.impl.StaticLoggerBinder no longer exists in SLF4J 2.x
(see [http://www.slf4j.org/codes.html#StaticLoggerBinder).] Ideally, Spark
should not have a hard dependency on an SFL4J 1.x impl classes.
Perhaps reflection or NoClassDefFoundError try-catch blocks could be used in
the logger detection code, so both SLF4J 1.x and 2.x could be supported at
runtime.
