Description

2 optional properties in yarn-site,

yarn.timeline-service.read.allowed.users
<queue>.acl_application_max_priority

are of the form

<user1>,<user2>..<white_space><group1>,<group2>..

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

<group1>,<group2>

instead of,

 <group1>,<group2>

when comparing 2 config versions.
