Apache NiFi - Administration
Apache NiFi offers support to multiple tools like ambari, zookeeper for administration purposes. NiFi also provides configuration in nifi.properties file to set up HTTPS and other things for administrators.
zookeeper
NiFi itself does not handle voting process in cluster. This means when a cluster is created, all the nodes are primary and coordinator. So, zookeeper is configured to manage the voting of primary node and coordinator. The nifi.properties file contains some properties to setup zookeeper.
