Thanks for reply Joe... Yes you understood my question/doubt well...I also saw the link - https://issues.apache.org/jira/browse/KAFKA-188
This is the same reason I mentioned in my previous mail in brackets >(One thing I understood that from kafka-0.8.0-beta1 version,Kafka is supporting > multiple log-directory,so that might be the reason for change of log.dir to > log.dirs). Can you please provide me the link where I can see other changes in Jira for brokerid to broker.id and zk.connect to zookeeper.connect and their corresponding reasons. #2 - JMX_PORT to use is checked in the (if [ $JMX_PORT ]; then) kafka-run-class.sh file.Also the default value of JMX_PORT is taken as "9999".But what if I want to change this port,where should I configure this. Please let me know if something is not clear.
