> Offline partition state not propagated by controller
> ----------------------------------------------------
>
> Key: KAFKA-8152
> URL: https://issues.apache.org/jira/browse/KAFKA-8152
> Project: Kafka
> Issue Type: Bug
> Reporter: Jason Gustafson
> Assignee: Jason Gustafson
> Priority: Major
>
> Currently when the controller starts up, only the state of online partitions
> will be sent to other brokers. Any broker which is started or restarted after
> the controller will see only a subset of the partitions of any topic which
> has offline partitions. If all the partitions for a topic are offline, then
> the broker will not know of the topic at all. As far as I can tell, the bug
> is the fact that `ReplicaStateMachine.startup` only does an initial state
> change for replicas which are online.
> This can be reproduced with the following steps:
> # Startup two brokers
> # Create a single partition topic with rf=1
> # Shutdown the broker where the replica landed
> # Shutdown the other broker
> # Restart the broker without the replica
> # Run `kafka-topics --describe --bootstrap-server \{server ip}`
> Note that the metadata inconsistency will only be apparent when using
> `bootstrap-server` in `kafka-topics.sh`. Using zookeeper, everything will
> seem normal.
