             Project: Ambari
          Issue Type: Bug
          Components: ambari-admin
    Affects Versions: 3.0.0

            Priority: Critical
             Fix For: 3.0.0


yarn.timeline-service property enabled overriding preset secure blueprint 
config for the same.

Configuration in yarn-site in blueprint

{code:java}
"yarn.timeline-service.enabled": "false"
{code}

The same config resolved in TOPOLOGY_RESOLVED yarn-site to 

{code:java}
"yarn.timeline-service.enabled": "true"
{code}

Configuration recommendation strategy in while cluster deploy template is 
ALWAYS_APPLY_DONT_OVERRIDE_CUSTOM_VALUES

{code:java}
"config_recommendation_strategy": "ALWAYS_APPLY_DONT_OVERRIDE_CUSTOM_VALUES",
{code}

Expected behavior: The config yarn.timeline-service.enabled should have 
persisted the value "false" even after deploy.
Actual behavior: Flag "yarn.timeline-service.enabled" is toggled to "true" 
while resolving configs.
