Description

My organization has NiFi instances with identical flows running in different environments and we would like to take advantage of the ability to substitute values from the Variable Registry into processor properties. This works great for fields like 'Topic Name' in PutKafka that support Expression Language (EL), but it does not work for fields like 'Known Brokers' that do not support EL.

Would it be worth my while to enable EL for these fields and issue a Pull Request, or is there another approach in mind for allowing these fields to be populated from the Variable Registry? Thanks for the information.
