Currently, NiFi is designed for static clusters, with frequent references in configuration files to a priori knowledge of node hostnames, ports, etc.
Efforts should be taken to make NiFi easier to dynamically scale. This can involve containerization improvements via Docker/rkt, deployment improvements via Kubernetes, and abstraction of the configuration values needed to stand up the cluster. A node should be able to join the cluster, and, given the correct keystore and truststore, immediately communicate with other existing nodes in the cluster without requiring direct configuration changes to them, or a restart of any node.

- permissions (RW on /proxy)
