Dear Team Members
Currently we are using Kafka 0.10.1, Zookeeper 3.4.5 versions, we are planning to upgrade to Kafka 2.2.0 version. We have 3 node Kafka cluster(3 Zookeeper nodes , 3 Kafka nodes) As suggested by you, Can I follow these steps 1. First, I have to download, new Kafka 2.1.0 tar file, and untar that file. In config directory server.properties I have to add the below new two parameters inter.broker.protocol.version=0.10.1 log.message.format.version=0.10.1 1. After that stop old Kafka broker version(0.10.1) and then start new Kafka broker (2.2.0) in one node. During this 1st node running with latest version and remaining two nodes are running with old version. And then stop old Kafka in second node, and then start new Kafka broker (2.2.0) node, Same thing we have to do it remaining third. Now all three Kafka nodes are running with new version 2.2.0 1. After that in server.proeprties we have to add update the below parameter inter.broker.protocol.version=2.2.0 same thing we have to do it remaining nodes now we have to do rolling restart in all three nodes. Now all three nodes are upgrading to new version ?????? 1. What I’m set for below parameter, right now we are not set this parameter into server.properties. Can I add this parameter ??? ssl.endpoint.identification.algorithm what is value should I mention for that above parameter???????? Please tell me if anything can I miss or else any extra steps are required.

Recently i upgraded only 10 node Kafka Cluster in production. Some of the Key Notes : 1) You need to set inter.broker.protocol.version = 1.1.0( Your Current Broker Version ) 2) Start upgrading your brokers one by one & Verify the overall functionality of your Cluster . Do not forget to verify the Clients too. 3) After Completing upgrade , set the version to 2.2.0 if you are upgrading latest version & restart brokers one by one. Pls be aware you cant downgrade after this step. 4) Pls keep in mind : The default value for ssl.endpoint.identification.algorithm was changed to https. So you need to set ssl.endpoint.identification.algorithm = empty to make it work as previous version of broker. Go through the documentation and you will more information (1.5 Upgrading >From Previous Versions) https://kafka.apache.org/documentation/#upgrade . being upgrade can we pointing old logs directory?? Not sure if i understand this question. In general , you dont need to change any Kafka Logs directory for broker upgrade. --Senthil On Fri, Apr 26, 2019 at 6:28 PM M.
