I think what is happening is you are using an older log4j.properties file with a newer hadoop. Since many classes are renamed, gone, you tend to get lots of output. FSAuditSystem something is always a good culprit for this. You can use the LogLevelServlet to change these at runtime without restarting then make the related changes to the log4j.properties.
