Hi Alexander,
Where are you looking for the logs? The output of the tasks should be in
$HADOOP_LOG_DIR/userlogs/attempt*/{stdout,stderr,syslog}.
Could you provide the exact java command line your tasks are running with
(do 'ps -ef | grep Child' on one of the nodes when the job is running).

depends on the classpath. You can do it in your own code by getting
whatever classloader you use then call getResource("log4.properties"

BTW, is hadoop planning to migrate on this stack from the deprecated
Apache commons and log4j?

Not necessarily. Hadoop code uses commons logging which defaults to going
to log4j, but lets you plug in different back ends via JVM properties.
This lets you do some tricks with log aggregation.
If changes to
you should use the log4j rather than the apache common logging

Where are you looking for the logs?
They will be available in Tasklogs. You can view them from web ui from
taskdetails.jsp page.

Hi all.

I need to log statements from the running job, e.g. use Apache commons
logging to print debug messages on map and reduce operations. I've tuned
the conf/log4.properties file for my logging domain but
