Description

In the attached example back pressure does not get applied if executed on a NiFi cluster. Single node works fine. I've reproduced this locally on a Redhat 7 based cluster with embedded zookeeper and a Kubernetes based cluster running external zookeeper.

This has been reproduced both with the embedded zookeeper with 1.11 and external docker based zookeeper from docker.io/bitnami/zookeeper:3.5.6-debian-10-r0
