Connecting NiFi to ZooKeeper
NiFi in cluster mode requires a ZooKeeper ensemble for state management and leader election purposes, this operator at the moment does not support single node deployments without ZooKeeper, hence this is a required setting.
spec: clusterConfig: zookeeperConfigMapName: simple-nifi-znode
Configuration happens via a ConfigMap, which needs to contain two keys called
ZOOKEEPER_HOSTS with the value being the ZooKeeper connection string and
ZOOKEEPER_CHROOT with the value being the ZooKeeper chroot. This ConfigMap typically is created by a ZookeeperZnode of the ZooKeeper Operator.
