Description

We really need to create a simple guide for how to build custom processor in nifi. The sort of 'hello world' example.

This was created due to finding it hard to give a nice simple short pointer for a question on the mailing list.

We do have a solid developer guide here [1] that goes into the key concepts and processor development a bit. The next best thing is to use the supplied maven archetype to lay down the fundamental pieces. You can read a bit more about that here [2]. Finally something that is also quite helpful is looking at the standard processors to see if anything follows the pattern/problem you had in mind and which can serve as a good basis [3]
