Release 3.0.0

NiFi deployed by Cloudera Flow Management Operator for Kubernetes is now secure by default. When no authorization method is provided, NiFi will be configured in single user auth mode with username "demonstration-user" and password "demonstration-password". When no Node Certificate Generation is specified, node certificates will be generated using a self-signed Cluster Issuer nifi-node-certs that is deployed with the operator.

If a NiFi cluster lost all viable leaders during scale up (usually a single node cluster scaling to two nodes), the new Node would begin waiting for leader election, eventually time out, and declare itself the leader with an empty flow definition. When the old leader finally recovered, it would take the empty flow of the leader, assuming it had no data in queues. Cloudera Flow Management Operator for Kubernetes now temporarily reverts the scale up if there is no viable leader at any point in the scale up process.
