[jira] [Commented] (KAFKA-705) Controlled shutdown doesn't seem to work on more than one broker in a cluster

    [ https://issues.apache.org/jira/browse/KAFKA-705?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13555359#comment-13555359 ]

Neha Narkhede commented on KAFKA-705:
-------------------------------------

>> Would you by any chance be able to provide a scenario to reproduce this locally?

I would suggest you try out on a distributed environment that is setup on a large amount of partitions and traffic. Since it is internal, I can pass on the connection url to you.

> 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.
