aeaversa commented on issue #3281: NIFI-5986 Adding "Stop & Configure" button functionality to Processor… URL: https://github.com/apache/nifi/pull/3281#issuecomment-462846448 @mcgilman @moranr - I went ahead and updated the code to allow the Processor Configuration/Details dialog(s) to support the display of threads and bulletins in the same style as is displayed on the processors on the canvas. A terminate prompt is on the Processor Configuration dialog "Apply" button as well, such that should the end user hit "Apply" and threads are still active, it will simply provide them an option to terminate or wait for the threads to finish normally. I believe this is a good solution to allow threads to naturally close out in the background as the user is making their changes. I did not institute an additional polling process to inspect the thread state, but rather simply synced the thread state value off the current canvas value for the component, since that interface already has a polling process active. Additionally, per @mcgilman suggestion, I added the Stop & Configure option to the context menu as well. Please take a test drive and let me know your feedback whenever you guys get a chance. My thanks again for all your help with this.
