Neha Narkhede commented on KAFKA-1298:
--------------------------------------
@sriharsha I'm not sure that we've fixed the single replica problem with
controlled shutdown. I think what we need to do for this JIRA is-
1. Fix the single replica controlled shutdown issue
2. Remove the jmx hook from KafkaController
3. Remove the ShutdownBroker tool
4. Default to controlled shutdown in the broker config.
> Controlled shutdown tool doesn't seem to work out of the box

> Presumably this is because we stopped setting the JMX port by default. This
> is good because setting the JMX port breaks the quickstart which requires
> running multiple nodes on a single machine. The root cause imo is just using
> RMI here instead of our regular RPC.
