The Hadoop image routes the NM daemon process output to the container's stdout/stderr, so /var/log/hadoop/*.log is always empty. The diagnostic dump for the NM daemon log has been removed since it was always producing (no output found). The three remaining dumps (launch_container.sh, container syslog, stdout/stderr/prelaunch.err) all target /var/log/hadoop/userlogs/ and are populated by a real Tez run. -- This is an automated message from the Apache Git Service.
