[Pki-users] log4j error when creating new user.

I'm getting the below error message when attempting to add a new user. Where should I be looking to troubleshoot this issue? root@newca:~# pki -c Secret123 -n caadmin ca-user-add newuser --fullName "New User" log4j:WARN No appenders could be found for logger (org.jboss.resteasy.plugins.providers.DocumentProvider). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
