Hi. We are testing hadoop. We are using hadoop (0.20.2-cdh3u3). I am using the cotomized conf directory with -"-config mypath". I modified the log4j.properties file in this path, adding " log4j.logger.com.mycompany=DEBUG". It works fine with our pseudo-one-node-cluster setup (1.00). But in the new cluster (with 32 data nodes/name node/secondary namenode/jobtracker/backup jobtracker), I can only see the log from hadoop (in the web interface, when I navigate all the way into the task node log), but no logs from my mapper/reducer (com.mycompany.***) show up. I can do System.out.println or System.err.println and see them in the same log file, but no logs from log4j show up. Is there any other configuration I missed? Thanks.
