Gour Saha created AMBARI-23291:
----------------------------------
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.
