ODL doesn't write log to karaf.log properly after startup. All DG log is not written into karaf.log, which makes the debug very hard.

There is a workaround provided by Alexis for the time being:

Delete the follwoing lines in the statefulset definition by running command `kubectl edit statefulset onap-sdnc-sdnc`

• mountPath: /opt/opendaylight/current/etc/org.ops4j.pax.logging.cfg
  name: sdnc-logging-cfg-config
  subPath: org.ops4j.pax.logging.cfg

Then you need to kill the sdnc pod,
`kubectl delete pod dev-sdnc-sdnc-0 -n onap`
