Hello list, I am trying to add some functionality to Hadoop-core and I am
having serious issues
debugging it. I have searched in the list archive and still have not been
able to resolve the issues.
Simple question:
If I want to insert "LOG.INFO()" statements in Hadoop code is not that as
simple as modifying
log4j.properties file to include the class which has the statements. For
example, if I want to
print out the LOG.info("I am here!") statements in MapTask. class
I would add to the lo4j.properites file the following line:
LOG.info statements in MapTask will be shown in syslog in task logs.
The directory is ${hadoop.log.dir}/userlogs/<attemptid>.
The same can be browsed on the web ui of the task.

log4j.logger.org.apache.hadoop.mapred.MapTask=INFO
This approach is clearly not working for me.
What am I missing?
Thank you,
