After the upgrade is complete, verify the following properties in Kafka
(kafka-broker) using Ambari:
-
inter.broker.protocol.version
-
log.message.format.version
-
Go to Ambari and locate the
inter.broker.protocol.version and
log.message.format.version properties.
-
Verify the values of the properties.
-
inter.broker.protocol.version must be set to the
latest Kafka version. For example, inter.broker.protocol.version =
2.1
log.message.format.version must be set to the version
you set before upgrade. For example, log.message.format.version = 2.0 or
1.1 or 1.0.
-
If you find any performance degradation, perform proper evaluation and set the
value of the
log.message.format.version property to the latest
Kafka version, which is 2.1, and perform rolling restart for your
kafka-broker.
