Upgrading from kafka_2.9.2-0.8.1.1 to kafka_2.11-0.10.0.0
The new version kafka will look at the same location for log files as older one is what I am assuming. As per documentation following properties will be set in the new broker inter.broker.protocol.version=0.8.1.1 log.message.format.version=0.8.1.1 In case if something goes wrong, is it possible to stop new broker and start old ones again ? Any potential risks involved in this ? or it is not supported at all ? Any other suggestions to achieve this by somebody who has already done it ?
