Description copied from interface: BlueprintValidator

Validate blueprint topology.

Specified by:

validateTopology in interface BlueprintValidator

Throws:

InvalidTopologyException - if the topology is invalid

validateRequiredProperties

public void validateRequiredProperties()
                                throws InvalidTopologyException,
                                       GPLLicenseNotAcceptedException

Description copied from interface: BlueprintValidator

Validate that required properties are provided. This doesn't include password properties.

Specified by:

validateRequiredProperties in interface BlueprintValidator

Throws:

InvalidTopologyException - if required properties are not set in blueprint

GPLLicenseNotAcceptedException - ambari was configured to use gpl software, but gpl license is not accepted

verifyComponentCardinalityCount

public Collection<String> verifyComponentCardinalityCount(String component,
                                                          Cardinality cardinality,
                                                          AutoDeployInfo autoDeploy)

Verify that a component meets cardinality requirements. For components that are auto-install enabled, will add component to topology if needed.

Parameters:

component - component to validate

cardinality - required cardinality

autoDeploy - auto-deploy information for component

Returns:

collection of missing component information

isDependencyManaged

protected boolean isDependencyManaged(Stack stack,
                                      String component,
                                      Map<String,Map<String,String>> clusterConfig)

Determine if a component is managed, meaning that it is running inside of the cluster topology. Generally, non-managed dependencies will be database components.

Parameters:

stack - stack instance

component - component to determine if it is managed

clusterConfig - cluster configuration

Returns:

true if the specified component managed by the cluster; false otherwise
