Just fixed KYLIN-457 and deprecated the old (many) log4j.properties. - Under the common module, old log4j.properties is renamed to *kylin-log4j.properties*. DebugTomcat use it, log to console only. - Under the server module, old log4j.properties is renamed to *kylin-server-log4j.properties*. This is used by kylin server, log to file system. - Other log4j config files are all removed.
So no more confusions around which log4j.properties is being used. Cheers Yang
