----------------------------------

             Summary: Ambari should prevent override of cluster level configs which cannot be overridden by custom config groups
                 Key: AMBARI-23291
                 URL: https://issues.apache.org/jira/browse/AMBARI-23291
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: trunk, 2.6.0
            Reporter: Gour Saha


Ambari currently allows override of certain cluster-wide config properties like "CPU scheduling" (by setting the value of config property _yarn.scheduler.capacity.resource-calculator_ to _org.apache.hadoop.yarn.util.resource.DominantResourceCalculator_
and few other properties). CPU scheduling cannot be overridden by custom config groups and restricted to a subset of hosts. Hence, the Ambari UI should block the override of such configs. Otherwise, the end-user will think that override of such features are supported.
