Descriptions

In Apache NiFi 1.2.0 to 1.11.4, the NiFi UI and API were protected by mandating TLS v1.2, as well as listening connections established by processors like ListenHTTP, HandleHttpRequest, etc. However intracluster communication such as cluster request replication, Site-to-Site, and load balanced queues continued to support TLS v1.0 or v1.1.

En Apache NiFi versiones 1.2.0 hasta 1.11.4, la Interfaz de Usuario y la API de NiFi estaban protegidas al exigir TLS versión v1.2, así como las conexiones de escucha establecidas por procesadores como ListenHTTP, HandleHttpRequest, etc. Sin embargo, la comunicación intracluster, como la replicación de peticiones de clúster, Site -to-Site, y las colas de balanceo de carga continuaban admitiendo TLS versión v1.0 o v1.1
