> Mahout jobs produce a lot of output on the command line and log messages like
> these below are distracting:
> attempt_201311181700_0002_m_000000_0: SLF4J: Class path contains multiple
> SLF4J bindings.
> attempt_201311181700_0002_m_000000_0: SLF4J: Found binding in
> [jar:file:/home/hadoop/lib/slf4j-log4j12-1.7.4.jar!/org/slf4j/impl/StaticLoggerBinder.class]
> attempt_201311181700_0002_m_000000_0: SLF4J: Found binding in
> [jar:file:/mnt/var/lib/hadoop/mapred/taskTracker/hadoop/jobcache/job_201311181700_0002/jars/job.jar!/org/slf4j/impl/StaticLoggerBinder.class]
> attempt_201311181700_0002_m_000000_0: SLF4J: See
> http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
> attempt_201311181700_0002_m_000000_0: SLF4J: Actual binding is of type
> [org.slf4j.impl.Log4jLoggerFactory]
> Let's silence log messages like these that do not provide information about
> the Mahout job itself. If you have more instances of superfluous logging add
> this to the issue.
