hi there I have a proposal which may change behavior of kafka-server-stop.sh, this script kill all instance on the host without any confirm, someone may just want to kill the single one, so maybe a confirm when find multy instance is more safer. already create a issue(https://issues.apache.org/jira/browse/KAFKA-9709) and pull request(https://github.com/apache/kafka/pull/8275), more detail can be found there. a KIP is necessary too, so request for the permission to do so, my wiki id(login name) is 67
