In document
Users can determine which node is currently elected as the Primary Node by looking at the Cluster Management page of the User Interface.
But there is no way to do this in nifi 1.0.0.(but nifi 0.7.0 can do it)

Hello,
In Apache NiFi 1.0 there are no longer UI controls or API calls exposed to change whether or not a node is the primary or cluster coordinator because they are now automatically elected and maintained by the zero master clustering model backed by Zookeeper. It is the case that any node at any time should be capable to take on those designations. This ensures that we don't need any special nodes and that we're able to always have these valuable roles active from an HA perspective - which was not the case previously.
Thanks Joe
