How to perform a controlled shutdown for rolling bounce?

Running 0.8.1 and am unable to do a controlled shutdown as part of a
rolling bounce.

Is this the primary reference for this task?

https://cwiki.apache.org/confluence/display/KAFKA/Replication+tools#Replicationtools-1.ControlledShutdown

I've set the config to enable controlled shutdown.

controlled.shutdown.enable=true
controlled.shutdown.max.retries=3
controlled.shutdown.retry.backoff.ms=5000

Before shutting down the first broker, topics looks like:

Topic:events PartitionCount:2 ReplicationFactor:1 Configs:
Topic: events Partition: 0 Leader: 1 Replicas: 1 Isr: 1
Topic: events Partition: 1 Leader: 2 Replicas: 2 Isr: 2
Topic:failure PartitionCount:2 ReplicationFactor:1 Configs:
Topic: failure Partition: 0 Leader: 1 Replicas: 1 Isr: 1
Topic: failure Partition: 1 Leader: 2 Replicas: 2 Isr: 2
Topic:retry PartitionCount:2 ReplicationFactor:1 Configs:
Topic: retry Partition: 0 Leader: 2 Replicas: 2 Isr: 2
Topic: retry Partition: 1 Leader: 3 Replicas: 3 Isr: 3

I then executed the bin/kafka-server-stop.sh program.

After that, the topics look like:

Topic:events PartitionCount:2 ReplicationFactor:1 Configs:
Topic: events Partition: 0 Leader: -1 Replicas: 1 Isr:
Topic: events Partition: 1 Leader: 2 Replicas: 2 Isr: 2
Topic:failure PartitionCount:2 ReplicationFactor:1 Configs:
Topic: failure Partition: 0 Leader: -1 Replicas: 1 Isr:
Topic: failure Partition: 1 Leader: 2 Replicas: 2 Isr: 2
Topic:retry PartitionCount:2 ReplicationFactor:1 Configs:
Topic: retry Partition: 0 Leader: 2 Replicas: 2 Isr: 2
Topic: retry Partition: 1 Leader: 3 Replicas: 3 Isr: 3

What does the -1 for Leader and blank Isr indicate? Do I need to run
something else for the leader election to occur? I thought that was
automatic with the controlled shutdown enabled. Is there a different
shutdown command to issue?

Thanks!
