-----------------------------------
Summary: fix default InterBrokerProtocolVersion
Key: KAFKA-2149
URL: https://issues.apache.org/jira/browse/KAFKA-2149
Project: Kafka
Issue Type: Bug
Reporter: Onur Karaman
Assignee: Onur Karaman
Fix the default InterBrokerProtocolVersion to be KAFKA_082 as specified in
KIP-2.
We hit wire-protocol problems (BufferUnderflowException) with upgrading brokers
to include KAFKA-1809. This specifically happened when an older broker receives
a UpdateMetadataRequest from a controller with the patch and the controller
didn't explicitly set their inter.broker.protocol.version to 0.8.2
