NiFi on Mac --> MiNiFi on RPi --> LED + Other devices etc.
Operations
- NiFI polls MiNiFi to check on the status of LED and other devices
- MiNiFi runs those commands and sends the info back to NiFi
- NiFi stores the info in HBase, which is queried by Ambari to show the current status of LED and other device.
- NiFi also exposes an API that can be used by Ambari Views. The API will send DNP message to MiNiFi to take action on LED and change its status.
