    Description

      Based on discussions in YARN-10652, it is clear that usage of a "." (dot) in a username/groupname (e.g. users in AD/LDAP) can cause unexpected issues e.g. placement rules involving username (%user placeholder) will definitely exhibit unexpected behavior.

      As such, we need to document clearly for our customers that this use-case is strictly not recommended in CapacityScheduler.
