Hi guys,

This has been solved. These emails are from last week when the mailing list didn’t work.

Spark 0.9.1 does not depend on log4j-over-slf4j (here is the SBT file for 0.9.1). Are you sure that no other dependency in your project is bringing in dependency in the classpath? Alternatively, if you dont want slf4j-log4j12 from spark, you can safely exclude in the dependencies.

I recall someone from the Spark team (TD?) saying that Spark 9.1 will change the logger and the circular loop error between slf4j and log4j wouldn’t show up.

 

Yet on Spark 9.1 I still get

SLF4J: Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar on the class path, preempting StackOverflowError.

SLF4J: See also http://www.slf4j.org/codes.html#log4jDelegationLoop for more details.

 

Any solutions?
