> Can't set SSL as inter-broker-protocol by rolling restart of brokers
> --------------------------------------------------------------------
>
> Key: KAFKA-2738
> URL: https://issues.apache.org/jira/browse/KAFKA-2738
> Project: Kafka
> Issue Type: Bug
> Reporter: Gwen Shapira
> Assignee: Ben Stopford
> Priority: Blocker
> Fix For: 0.9.0.0
>
>
> Scenario (as carefully documented by [~benstopford]:
> 1. Start 2 or more brokers with listeners on both PLAINTEXT and SSL
> protocols, and PLAINTEXT as security.inter.broker.protocol:
> inter.broker.protocol.version = 0.9.0.X
> security.inter.broker.protocol = PLAINTEXT
> listeners = PLAINTEXT://:9092,SSL://:9093
> 2. Stop one of the brokers and change security.inter.broker.protocol to SSL
> inter.broker.protocol.version = 0.9.0.X
> security.inter.broker.protocol = SSL
> listeners = PLAINTEXT://:9092,SSL://:9093
> 3. Start that broker again.
> You will get replication errors as it will attempt to use SSL on a PLAINTEXT
> port:
