How do I enable debug mode
Hello,
I have below code in mapreduce program.
if(logger.isDebugEnabled()){
logger.info("Mapper value =" + value);
}
How do I enable debug mode to print "Mapper value =" in the logs.
I tried modifying hadoop-2.5.1/etc/hadoop/ log4j.properties, and it still doesn't work.
Thanks
