Hi, I have two doubts for changes in different versions of Kafka available:
*Doubt1:* I am using Kafka from the version kafka-0.7.1-incubating-src.tgz. The latest stable version is kafka_2.8.0-0.8.0.tar.gz. But there is propertyName difference in config/server.properties file of different versions. *kafka-0.7.1-incubating-src.tgz and kafka-0.7.2-incubating-src.tgz have below property(ies) :* brokerid = 0 log.dir = /tmp/kafka-logs zk.connect=localhost:2181 *But kafka-0.8.0-beta1-src.tgz have as below :* broker.id = 0 log.dir = /tmp/kafka-logs zookeeper.connect=localhost:2181 *But kafka_2.8.0-0.8.0.tar.gz have as below: * broker.id = 0 log.dirs = /tmp/kafka-logs zookeeper.connect=localhost:2181 So May I know why the difference in property-Name of different versions(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). *Doubt2:* /bin/kafka-server-start.sh file export JMX_PORT till version kafka-0.8.0-beta1-src.tgz,but in stable latest version it is not exporting JMX_PORT.So why this has been done.
