Hadoop uses Commons Logging:

http://jakarta.apache.org/commons/logging/

One should be able to configure it to use other logging backends or a null logger:

http://jakarta.apache.org/commons/logging/commons-logging-1.1/guide.html#Configuration

Please tell us how this works.

Hello,

We're trying to experiment with Hadoop running in a restricted
java environment. Is there a way of bypassing logging entirely so that
a log4j jar is not needed?

Thanks,
