>             Project: Ambari
>          Issue Type: Task
>          Components: ambari-web
>    Affects Versions: 2.7.1
>            Reporter: Antonenko Alexander
>            Assignee: Antonenko Alexander
>            Priority: Major

>
> 2 optional properties in yarn-site,
> {noformat}
> yarn.timeline-service.read.allowed.users
> <queue>.acl_application_max_priority
> {noformat}
> are of the form
> {noformat}
> <user1>,<user2>..<white_space><group1>,<group2>..
> {noformat}
> Here the users are optional. Hence only groups could be specified with a leading space followed by <group1>,<group2>..
> But after setting such a configuration, Ambari strips the leading space and shows them as
> {noformat}
> <group1>,<group2>
> {noformat}
> instead of,
> {noformat}
>  <group1>,<group2>
> {noformat}
> when comparing 2 config versions.
