-----------------------------------------
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.
