Subject [24/50] [abbrv] git commit: ACCUMULO-2383 Add log4j properties support
Date Fri, 09 May 2014 15:29:02 GMT
ACCUMULO-2383 Add log4j properties support

Accumulo now looks for either XML or properties files for the Log4J configuration. It will
also heed the log4j.configuration isystem property if it is set. Its MonitorLog4jWatcher
can now load either properties or XML.
