#Console Appender

log4j.appender.CA.layout=org.apache.log4j.PatternLayout
log4j.appender.CA.layout.ConversionPattern=%-4r [%t] %-5p %c %x – %m%n

# Set the logger level of File Appender to WARN
log4j.appender.EXECUTION_LOG.Threshold = WARN

#File Appender
log4j.appender.EXECUTION_LOG=org.apache.log4j.RollingFileAppender
log4j.appender.EXECUTION_LOG.File=./Logs/sample.log
log4j.appender.EXECUTION_LOG.MaxFileSize=2MB
log4j.appender.EXECUTION_LOG.MaxBackupIndex=2

But what if you delete the logfile after log4j already wrote some logs? log4j is not going to create a new logfile. Instead, all following logs will be lost. Is there any chance to avoid this?
