----------------------------------------
Summary: Remove messy dependencies to log4j
Key: SPARK-5524
URL: https://issues.apache.org/jira/browse/SPARK-5524
Project: Spark
Issue Type: Bug
Reporter: Jacek Lewandowski
There are some tickets regarding loosening the dependency on Log4j, however
some classes still use the following scheme:
{code}
if (Logger.getLogger(classOf[SomeClass]).getLevel == null) {
Logger.getLogger(classOf[SomeClass]).setLevel(someLevel)
}
{code}
This doesn't look good and make it difficult to track why some logs are missing
when you use Log4j and why they are flooding when you use something else, like
logback.
There is a Logging class which checks whether we use Log4j or not. Why not
delegate all of such invocations, where the Logging class could handle it
properly, maybe considering more logging implementations?
