             Summary: HDP 2.6.5 Upgrade Requires a Pre-Upgrade Configuration 
Validation Check for Kafka
                 Key: AMBARI-23417
                 URL: https://issues.apache.org/jira/browse/AMBARI-23417
             Project: Ambari
          Issue Type: Task
            Reporter: Dmytro Grinenko


kafka-broker have two new properties:

- inter.broker.protocol.version
- log.message.format.version

These configurations must exist and have a value before proceeding with upgrade 
(the value for both should be aligned with the Kafka version on the current 
stack). We need validation at minimum to check for the existence of these 
parameters . Additional validation includes the following

For inter.broker.protocol.version :
value is not empty
value is set to current Kafka version in the stack (e.g. for HDP 2.6.x value 
should be 0.10.1, HDP 2.5.x should be 0.10.0, HDP 2.3x - 2.4x should be 0.9.0)

For log.message.format.version:
value is not empty (version can vary from current stack version)
