after cassandra startup I am getting at the console:
$ log4j:WARN No appenders could be found for logger (org.eclipse.jetty.util.log).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

how can I omit these console output (stdout) messages ?
(I tried and tried to figure out log4j-server.properties, with no success)
