Apache Nifi GetFTP Processor Dynamic input

Is it possible to pass dynamic properties like ftp host, port etc to GetFTP processor. I tried it but somehow GetFTP processor is not accepting any upstream connections. Basically I want to keep the ftp configuration for all the sources in one file and use just one GetFTP processor to read that information. Isn't it the correct way?

The Get* processors are source processors which do not accept input connections. For most applications there are complementary List* and Fetch* processors. The List* gets a list of objects that exist somewhere. Then a typical flow would pass that information to the Fetch* processor to grab the necessary files.

Correct me if I'm wrong but, what you want is a FetchFTP processor to pass FlowFiles to and evaluate the Hostname, port, filename, etc. using expression language.

While there are ListSFTP and FetchSFTP, currently there is no FetchFTP. There is a ticket open to create them[1] and a user recently emailed the mailing list offering them as a contribution[2] but I am waiting to hear back.

Update: The ListFTP and FetchFTP processors have been committed to master and will be in the next 1.X release
