Nifi node getting disconnected from cluster


Nifi node getting disconnected from cluster

New Contributor

Hi Team, we have a 3 node NIFI cluster and we are seeing one of the node getting disconnected from the cluster. When I looked at the logs(nifi-app.log) of the disconnected node, I dont see any heartbeat messages getting created and at the same time I dont see any errors too.

I tried to generate access token from this disconnected node, just to ensure that node is down even-though I see JVM process is up and running and I do see the access token getting generated.

Any help on why the node is getting disconnected and why the heart beat messages of below ones are not seeing in the logs of the disconnected node?
