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 2022-07-01 11:52:29,313 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 2022-07-01 11:52:34,792 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 😞         nifi.properties:   # Licensed to the Apache Software Foundation (ASF) under one or more # contributor license agreements.
