However since the Cassandra related logs get appended to a separate file, in case of Cassandra failure, the user doesn't see any error logs etc. in wso2carbon log or in terminal logs where Cassandra profile is running. Hence from users' perspective i think it is required to append the cassandra (or zookeeper) logs into wso2carbon.log file only when MB instance is started as a Cassandra or a Zookeeper server. If we append these to root logger of default log4j.properties file the logs will be displayed in non-profiled MB servers as well. That is why it is required to keep two log4j.properties files.
