> *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
