如何將log4j中的類靜音java.net.BindException

我正在使用apache spark，並且想要將運行我的spark-submit命令時拋出的java.net.BindException: Address already in use.異常靜音。 log4j屬性設置在下面貼出的單獨文件中。如何將log4j中的類靜音java.net.BindException

這裏是我的log4j.properties

log4j.rootCategory=WARN, console 
log4j.appender.console=org.apache.log4j.ConsoleAppender 
log4j.appender.console.target=System.err 
log4j.appender.console.layout=org.apache.log4j.PatternLayout 
log4j.appender.console.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{1}: %m%n 
log4j.logger.org.eclipse.jetty=WARN 
log4j.logger.org.eclipse.jetty.util.component.AbstractLifeCycle=ERROR 
log4j.logger.com.jiwire=INFO 
log4j.logger.com.nd=INFO

任何想法，我該怎麼做呢？
