小生最近在windows上搭建hadoop，按照官网的教程，应该是搭建起来了（单节点）：可以创建和删除hdfs上的文件，在eclipse里面也可以看到hdfs，如果我添加文件，eclipse里也会跟着更新，所以我觉得应该是搭建起来了，如果不是求大神指导。
问题是：在eclipse里我编写了wordcount代码（应该不会错的，我照着书上编的，是0.20.0版），然后使用run configurations设置Arguments来运行（hdfs://English.txt hdfs://test/）但是失败了，报错如下：
log4j:WARN No appenders could be found for logger (org.apache.hadoop.metrics2.lib.MutableMetricsFactory).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

求大神指教一二，帮小弟摆脱这个奇怪的问题！
