只顯示記錄由用戶

我使用SLF4J登錄信息，用火花和scala.How我可以顯示用戶插入的LOGG不整的火花日誌文件消息中插入的，這裏是log4j.properties只顯示記錄由用戶

# Here we have defined root logger 
log4j.rootLogger=ALL,R 


#Direct log messages to file 
log4j.appender.R=org.apache.log4j.RollingFileAppender 
log4j.appender.R.File=./logging.log 
log4j.appender.R.layout=org.apache.log4j.PatternLayout 
log4j.appender.R.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L- %m%n

什麼是火花
