Kevin Risden commented on NIFI-4472:
------------------------------------
Currently we use Ambari to managed HDF and the only Ambari alert is for the
NiFi process being down (pid not alive). We added a custom alert to Ambari to
check when an HDF node disconnects.
> add alerts when a node is disconnected in my NIFI cluster
