Mark Payne commented on NIFI-3122:
----------------------------------

Removed fix version because this is going to require a pretty significant rebase effort.

> 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.
