             Summary: Some configs with empty value shown on "Customize Service" page are not saved in the configuration type
                 Key: AMBARI-17877
                 URL: https://issues.apache.org/jira/browse/AMBARI-17877
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.4.0
            Reporter: Oleg Nechiporenko
            Assignee: Oleg Nechiporenko
            Priority: Critical
             Fix For: 2.4.0


*STR:*
# Start installer wizard and select HDP-2.5 stack and storm as a service
# On Customize Services page nimbus.impersonation.authorizer and nimbus.impersonation.acl are shown with empty values
# On deploying cluster, properties are not saved in storm-site

*Expected Result:* Properties like nimbus.impersonation.authorizer and nimbus.impersonation.acl does not have value tag defined in their stack definition. Such properties are received with value as null from API. Any property with null value should not be shown on "Customize Services" page unless stack advisor sets another value to the property
*Actual Result:* Properties with null value are shown as having empty string value on "Customize Services" page
