> 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
