Subject How do I enable debug mode
Date Thu, 04 Dec 2014 05:32:09 GMT
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
