Saving Kafka REST Configurations

Describes how Kafka REST configurations are saved during an upgrade.

Starting in EEP 6.0.0, the configuration for a previously installed version of Kafka REST is stored in a folder with a timestamp.
  • The configuration files are saved and overwritten by new configuration files when upgrading from:
    • 4.1.0 to 5.1.2
    • 5.1.2 to 6.0.0.0
  • The configuration files are saved only (not overwritten) when upgrading from:
    • 5.1.2 to 5.1.2

Example

The following example shows the list of configuration files that are saved when upgrading from mapr-kafka-rest 5.1.2 (EEP 7.0.0) to mapr-kafka-rest 5.1.2 (EEP 7.0.1):
ls /opt/mapr/kafka-rest/
kafka-rest-5.1.2  kafka-rest-5.1.2.0.202009100923  kafka-restversion

ls /opt/mapr/kafka-rest/kafka-rest-5.1.2.0.202009100923/config/
headers.xml  kafka-rest.properties  log4j.properties  warden.kafka-rest.conf
