SLF4J错误一直困扰着我一段时间.每次在显示命令输出之前键入任何hadoop shell命令时,它都会出现.
$ hadoop fs -ls
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further
details.
这是在Ubuntu 14.04上的cdh5的伪分布式安装.
