             Summary: spark-shell log level customization is lost if user provides a log4j.properties file
                 Key: SPARK-11929
                 URL: https://issues.apache.org/jira/browse/SPARK-11929
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core, Spark Shell
            Reporter: Marcelo Vanzin
            Priority: Minor


{{Logging.scala}} has code that defines the default log level for the spark-shell to WARN, to avoid lots of noise in the output.

But if a user provides a log4j.properies file in the Spark configuration, that customization is lost. That means that without a log4j.properties, there are two different configurations (one for regular apps, one for the shell). But if you have a custom file, you lose the ability to easily differentiate between those two, and you're stuck with a single config for both.

It would be nice to allow different configurations also in the second case.
