> Kafka broker restart failed due to below error:
> {noformat}
> raise Fail("Configuration parameter '" + self.name + "' was not found in configurations
dictionary!")
> resource_management.core.exceptions.Fail: Configuration parameter 'xasecure.audit.destination.db'
was not found in configurations dictionary!
> {noformat}
> Solution:
> During RU downgrade, <pre-upgrade/> runs on downgrade as well, which deleted {{xasecure.audit.destination.db}}
config property. 
> {noformat}
> <pre-upgrade>
>           <task xsi:type="configure" id="hdp_2_5_0_0_remove_ranger_kafka_audit_db"
/>
> </pre-upgrade>
> {noformat}
> Need to override it with a blank <pre-downgrade/> element.
