----------------------------------------
Summary: RU: Kafka brokers restart was stopped during downgrade
cluster
Key: AMBARI-18167
URL: https://issues.apache.org/jira/browse/AMBARI-18167
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.4.0
Reporter: Mugdha Varadkar
Assignee: Mugdha Varadkar
Priority: Blocker
Fix For: 2.4.0
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.
