Description
I'm getting warnings like this when starting jobs with bin/start-dfs.sh in Hadoop Core 0.21.0:
localhost: SLF4J: Class path contains multiple SLF4J bindings.
localhost: SLF4J: Found binding in [jar:file:/Users/srowen/Desktop/hadoop-core-0.21.0/lib/slf4j-log4j12-1.4.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
localhost: SLF4J: Found binding in [jar:file:/Users/srowen/Desktop/hadoop-core-0.21.0/lib/slf4j-simple-1.5.8.jar!/org/slf4j/impl/StaticLoggerBinder.class]
localhost: SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
Looks like one of the two jars should simply be removed. I removed the older log4j binding.
