刚才创建了新文件：log4j.properties，其中包含代码：

代码语言：javascript
复制
    hadoop.root.logger=DEBUG, console
log4j.rootLogger = DEBUG, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.target=System.out
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{2}: %m%n

谢谢，现在一切正常：D
