Hi Tomohiko, I gave you perms to edit the wiki.

> The hadoop.root.logger defined in log4j.properties is only used by applications. The
scripts (bin and daemons) always set it to HADOOP_ROOT_LOGGER or "INFO,console" so the installed
log4j.properties appears to be ignored. The wiki doesn't cover this:
> http://wiki.apache.org/hadoop/HowToConfigure
> We should update the cluster setup docs to indicate how the loglevel is configured and
also add a comment in log4j.properties that the hadoop.root.logger defined there is not used
by Hadoop itself, that HADOOP_ROOT_LOGGER must be set. This is relevant for commands and daemons,
though the latter also has daemonlog (http://hadoop.apache.org/common/docs/current/commands_manual.html#daemonlog).
