运行hadoop jar 包时出现以下错误提示；

Exception in thread "main" java.lang.NoSuchMethodError: org.slf4j.impl.StaticLoggerBinder.getSingleton()Lorg/slf4j/impl/StaticLoggerBinder;
   at org.slf4j.LoggerFactory.bind(LoggerFactory.java:128)

这是版本问题：

这里下载最新的jar文件并将slf4j-api-1.6.3.jar和slf4j-log4j12-1.6.3.jar这两个替换到hadoop安装目录下的lib文件夹下的旧版本之后搞定。
