Joel Koshy commented on KAFKA-705:
----------------------------------

I committed the fix to 0.8 with a small edit: used the 
liveOrShuttingDownBrokers field.

Another small issue is that we send a stop replica fetchers to the shutting 
down broker even if
controlled shutdown did not complete. This "prematurely" forces the broker out 
of the ISR of those
partitions. I think it should be safe to avoid sending the stop replica request 
if controlled shutdown
has not completely moved leadership of partitions off the shutting down broker.

                
> Controlled shutdown doesn't seem to work on more than one broker in a cluster

> I wrote a script (attached here) to basically round robin through the brokers 
> in a cluster doing the following 2 operations on each of them -
> 1. Send the controlled shutdown admin command. If it succeeds
> 2. Restart the broker
> What I've observed is that only one broker is able to finish the above 
> successfully the first time around. For the rest of the iterations, no broker 
> is able to shutdown using the admin command and every single time it fails 
> with the error message stating the same number of leaders on every broker.
