             Summary: Ambari Upgrade prcoess should preserve the old configs and add the new config options to the old config files.
                 Key: AMBARI-2290
                 URL: https://issues.apache.org/jira/browse/AMBARI-2290
             Project: Ambari
          Issue Type: Bug
          Components: controller
    Affects Versions: 1.2.5
            Reporter: Dmitry Sen
            Assignee: Dmitry Sen
            Priority: Critical
             Fix For: 1.2.5


The Ambari Upgrade process should preserve the old configs and add the new config options to the old config files.
Currently we have it the other way around, that we copy the needed 3 properties from the old config files - this is wrong. We need to use the older config file and add the new options to the old config file. This is because the older config file can have all kinds of config option that the user might have used. We have to really really keep in mind usability of the product when fixing issues.
