Hi Mark One needs to make sure all nodes in your cluster are added to the policy and not just the cluster coordinator.

Similarly, in order to successfully 'Empty queue', a user must be part of the 'modify the data'. However, in a Cluster configuration, it appears the Cluster Coordinator must also be in the relevant policy in order to be successful. Is this expected behavior? Apache NiFi 1.1.2
