             Summary: Allow templates to be instantiated even if they contain 
missing processor types
                 Key: NIFI-3122
                 URL: https://issues.apache.org/jira/browse/NIFI-3122
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
            Reporter: Mark Payne
            Assignee: Mark Payne
             Fix For: 1.2.0


If a template is imported into NiFi, no checks are done to see if the component 
types in the template are valid. However, when we try to instantiate the 
template, if it contains a processor, etc. that is not known by the NiFi 
instance, the instantiation fails.

We recently introduced the notion of Ghost Processors/Controller 
Services/Reporting Tasks. As a result, we can now avoid the failure in this 
case and instead create ghost components when the type is not known.
