> Controller getting stuck
> ------------------------
>
> Key: KAFKA-6013
> URL: https://issues.apache.org/jira/browse/KAFKA-6013
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.11.0.0, 0.11.0.1
> Reporter: Ivan Babrou
> Labels: reliability
>
> It looks like a new issue in 0.11.0.0 and 0.11.0.1 still has it.
> We upgraded one of the clusters from 0.11.0.0 to 0.11.0.1 by shutting down 28
> machines at once (single rack). When nodes came up none of them progressed
> after these log lines:
> {noformat}
> Oct 05 02:17:42 mybroker14 kafka[32940]: INFO Kafka version : 0.11.0.1
> (org.apache.kafka.common.utils.AppInfoParser)

> Oct 05 02:17:42 mybroker14 kafka[32940]: INFO [Kafka Server 10014], started
> (kafka.server.KafkaServer)
> {noformat}
> There was no indication in controller node logs that it picked up rebooted
> nodes. This happened multiple times during the upgrade: once per rack plus
> some on top of that.
> Reboot took ~20m, all nodes in a single rack rebooted in parallel.
> The fix was to restart controller node, but that did not go cleanly too:
> {noformat}

> KAFKA-5028 happened in 0.11.0.0, so it's likely related.
