For dev purposes, I run a small Kafka/Zookeeper setup, two brokers, one Zookeeper, all running on the same host. I wrote a small stop script which executes kafka-server-stop.sh on the two brokers, waits up to 20 seconds, checking every second to see if the brokers have both exited, then runs zookeeper-server-stop.sh.
The Zookeeper instance and one of the brokers never seems to exit. Before running the stop script, I stopped all my clients. I've confirmed with lsof that the only established IPv4 connections either has is with the other. I'm running from a kafka_2.11-1.0.0 download on a Red Hat 6 server. I don't routinely kill this setup, but when I do, it never seems to exit cleanly. I always wind up having to forcibly kill the remaining two processes. Am I doing something wrong? How long should shutdown typically take? Thanks, Skip Montanaro
