Jamie,

Sorry you didn't get a response.  I'm happy to confirm that this is the correct list for your question.  There is no well-beaten path for running NiFi in another process, NiFi assumes that it is deployed as it's own process.  NiFi contains a number of features for classloader isolation, thread management, and performance monitoring that may mean something different in another process, although I can't say for sure they will break.

Hopefully, some others can chime in on the pitfalls.

Thanks,

James
