    Description

      When I start the NameNode or DataNode using sbin/hadoop-daemon.sh, I get a variant of the following error on stdout:

      SLF4J: Class path contains multiple SLF4J bindings.
      SLF4J: Found binding in [jar:file:/Users/joecrow/Code/hadoop-0.23.0/share/hadoop/common/lib/slf4j-log4j12-1.5.11.jar!/org/slf4j/impl/StaticLoggerBinder.class]
