@Shu_ashu  this approach works has a problem that clear-state is working only on stopped processor.  I am using  ScrollElasticsearch processor and it needs to be cleared before it can be executed again.  I tried    curl -i -X POST http://localhost:8080/nifi-api/processors/0172101b-be82-11aa-1249-d1383cb1ceba/state/clear-requests    but it end-up with conflict status  I must stop processor in order to clear-state Do I really have to stop processor? manually or via API - it doesn't seems to me as a good design.
