             Summary: Min/Max/Step/etc from '/recommendations' API should override '/stacks' data
                 Key: AMBARI-10344
                 URL: https://issues.apache.org/jira/browse/AMBARI-10344
             Project: Ambari
          Issue Type: Task
          Components: ambari-web
    Affects Versions: 2.1.0
            Reporter: Andrii Babiichuk
            Assignee: Andrii Babiichuk
             Fix For: 2.1.0


Enhanced config {{yarn.nodemanager.resource.memory-mb}} has a maximum value of {{268435456 MB}} which comes from the static stack-definition of the config. However the real maximum of this config is given by the /recommendations call - which calculates it based on the machine's actual memory.
{code}
"yarn-site" : {
              "properties" : {
                "yarn.scheduler.minimum-allocation-mb" : "682",
                "yarn.scheduler.maximum-allocation-mb" : "2048",
                "yarn.nodemanager.resource.cpu-vcores" : "2",
                "yarn.nodemanager.resource.memory-mb" : "2048"
              },
              "property_attributes" : {
                "yarn.scheduler.minimum-allocation-vcores" : {
                  "max" : "2"
                },
                "yarn.scheduler.maximum-allocation-vcores" : {
                  "max" : "2"
                },
                "yarn.nodemanager.resource.memory-mb" : {
                  "max" : "2887"
                },
                "yarn.scheduler.minimum-allocation-mb" : {
                  "max" : "2048"
                },
                "yarn.nodemanager.resource.cpu-vcores" : {
                  "max" : "4"
                },
                "yarn.scheduler.maximum-allocation-mb" : {
                  "max" : "2048"
                }
              }
            }
{code}

Wherever configs are shown (installer, service-config, host-page, add-service, etc.), we need to override the static stack-default property_attributes with the /recommendations given property_attributes.
