             Summary: kerberos.json conf calculation may result in the whole macro be set as the property value when the macro contains non-existing property
                 Key: AMBARI-21215
                 URL: https://issues.apache.org/jira/browse/AMBARI-21215
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: trunk
            Reporter: Di Li
             Fix For: trunk


For the following example of kafka configuration in Kafka kerberos.json, the "advertised.listeners" line will have value "${kafka-broker/advertised.listeners|replace(\\bPLAINTEXT\\b, SASL_PLAINTEXT)}" if  "advertised.listeners" does not exit when enabling Kerberos. The value will be set correctly post keberos enabling if a user then adds the property and regenerate keberos keytabs.
