仅显示用户插入的日志

Question

我正在使用 slf4j 记录信息，使用 spark 和 scala。如何将用户插入的消息显示为 logg 而不是整个 spark 日志文件，这里是 log4j.properties

# 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

这里是 spark 显示的示例

 i want to see only message inserted by user 

这里是scalla代码

import org.apache.log4j.{Level, Logger}
Logger.getLogger("org").setLevel(Level.OFF)

任何帮助将不胜感激
