Koji Kawamura commented on NIFI-2363:
-------------------------------------
External state has the same characteristics, the same state is shared among
cluster nodes.
> CLUSTER scope state should be viewed/cleared from primary node

> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.0.0

> Fix For: 1.0.0
>
>
> Currently, every node in a NiFi cluster retrieves or clears CLUSTER scope
> state when user view/clear component state from NiFi UI.
> Since the cluster-wide state is shared the same value among nodes, those
> operation should be executed only from a primary node.
