Lewis John McGibbney commented on NUTCH-1188:
---------------------------------------------
Thank you for this patch. In the short term, when we get one other +1, I would
like to commit. Can I ask you to have a look @ NUTCH-1138 and comment on
whether the patch is any use for your activities. It is our vision to remove
LogUtil and use the Slf4j/Log4j framework for all logging.
Thank you very much for this patch.

> LogUtil has static fields,which is initialized like this:
> FATAL = Logger.class.getMethod("error", new Class[] { Object.class });
> but the Logger has no such method，the correct method is：
> void org.slf4j.Logger.error(String msg)
> So，LogUtil's static fields are not initialized correctly(they are null)
> -------------------------------
> Run crawl，you will find msg in hadoop.log：
