> Key: AMBARI-17626
> URL: https://issues.apache.org/jira/browse/AMBARI-17626
> Project: Ambari
> Issue Type: Bug
> Components: blueprints
> Affects Versions: trunk
> Reporter: Keta Patel
> Assignee: Keta Patel
> Attachments: AMBARI-17626.patch,
> cluster_with_defect_installed_from_blueprint.tiff,
> cluster_with_fix_insatlled_from_blueprint.tiff,
> original_cluster_used_to_create_blueprint.tiff
>
>
> Blueprints make use of a population strategy in the registration step to
> create JSON objects for properties and property-attributes. These properties
> and property-attributes get stored in the database (DB) in the
> "clusterconfig" table under "config_data" and "config_attributes"
> respectively. Format of these JSON objects is critical as the UI parses these
> objects assuming them to be in a certain format.
> At present property-attributes like "final" get stored in "clusterconfig"
> table in the format shown in attachment
> "original_cluster_used_to_create_blueprint.tiff".
> i.e. "final": {"attr1":"val1", "attr2":"val2"}
> When a new cluster is to be installed using a blueprint, after the blueprint
> is registered and the new cluster is installed using the registered
> blueprint, the format of "property-attributes" is as shown in attachment
> "cluster_with_defect_installed_from_blueprint.tiff".
> i.e. "attr1":{"final":"val1"}, "attr2":{"final":"val2"},
> "final":{"attr1":"val1", "attr2":"val2"}
> The population strategy is responsible for the "attr1":{"final":"val1"} and
> "attr2":{"final":"val2"}.
> The reason for "final":{"attr1":"val1", "attr2":"val2"} is because of a merge
> with the Parent Configuration during blueprint registration. This Parent
> Configuration comes from Stack using the XML files of the service properties.
> Because of this "final" attribute, the UI still shows the properties
> correctly and hence it went undetected.
> Proposed fix involves correcting the population strategy so that the
> attributes are placed in the correct format. After the fix, the new cluster
> installed via blueprint shows "property-attributes" as shown in attachment
> "cluster_with_fix_insatlled_from_blueprint.tiff"
> i.e. "final":{"attr1":"val1", "attr2":"val2"}
