How can I configure hadoop mapreduce so that the log of my mapreduce class can output to a file?

I modified the $HADOOP_HOME/conf/log4j.properies But it is not working as what I expect. How to solve this problem?

Check if you have other log4j.properties files in your classpath. A problem with log4j is that the only the last log4j.properties it reads from the classpath will be actually used. So if you have other log4j.properties files in the classpath, then one of those might be getting picked up. Try to merge all these log4j.properties files and it should work.

Also please post the content of the log4j.properties files if you can. There can be a problem there as well.
