Hi, I have been trying to setup up Hadoop logging at the task level but with no success so far. I have modified log4j.properties and set many parameters to DEBUG level (log4j.logger.org.apache.hadoop.mapred.Task=DEBUG log4j.logger.org.apache.hadoop.mapred.MapTask=DEBUG log4j.logger.org.apache.hadoop.mapred.ReduceTask=DEBUG
and log4j.logger.org.apache.hadoop = DEBUG ) but I cant see any LOG.info or LOG.debug messages from the tasks being recorded. This is with yarn being enabled. I am not sure what I have missed in the configurations to make it work properly. I think I should eventually get these messages in the nodemanager.out log file? Thanks in advance, Sherif
