Hey,
Maybe I don't understand the slf4j model completely, but I think you
need to add a concrete implementation of a logger. So in your case
you'd the logback-classic binding in place of the log4j binding at
compile time:

Hi Patrick,
Thanks for the patch. I tried building a patched version
of spark-core_2.10-0.9.0-incubating.jar but the Maven build fails:

Hey All,
We have a fix for this but it didn't get merged yet. I'll put it as a
blocker for Spark 0.9.1.

Hi, Sergey --
Here's my recipe, implemented via Maven; YMMV if you need to do it via sbt,
etc., but it should be equivalent:
1) Replace org.apache.spark.Logging trait with this:

Hi Sean,
We're not using log4j actually, we're trying to redirect all logging to
slf4j which then uses logback as the logging implementation.
The fix you mentioned - am I right to assume it is not part of the latest
released Spark version (0.9.0)? If so, are there any workarounds or advices
on ho
Yes I think that issue is fixed (Patrick you had the last eyes on it IIRC?)
If you are using log4j, in general, do not redirect log4j to slf4j.
Stuff using log4j is already using log4j, done.

Hi,
I'm trying to redirect Spark logs to slf4j. Spark seem to be using Log4J,
so I did the typical steps of forcing a Log4J-based framework to use slf4j
- manually excluded slf4j-log4j12 and log4j, and included log4j-over-slf4j.
When doing that however Spark starts failing on initialization with:
