NiFi Kubernetes cluster - ProtocolException: Failed marshalling 'HEARTBEAT' protocol message

Robybrown — Fri, 01 Jul 2022 12:29:38 GMT

Hi everybody!

I am struggling trying to create a NiFi Kubernetes cluster out of cetic helm chart.

After installation, I see a working zookeeper cluster (3 instances) and a 2 instances stateful set for NiFi. One instance is correctly elected as cluster coordinator, NiFi frontend shows me a 1 member cluster. The second instance's log keeps on popping messages such as:

2022-07-01 11:52:23,839 WARN [Clustering Tasks Thread-2] o.apache.nifi.controller.FlowController Failed to send heartbeat due to: org.apache.nifi.cluster.protocol.ProtocolException: Failed marshalling 'HEARTBEAT' protocol message

every five seconds.

I'm attaching the second pod's log and that pod's generated nifi.properties file.

Please help me 😞
