Description

In my cluster, I see the following Node events for a particular node:

07/28/2016 06:17:29 UTC: Acquired role [Cluster Coordinator]

07/28/2016 04:53:30 UTC: Node Status changed from CONNECTING to DISCONNECTED due to org.apache.nifi.controller.UninheritableFlowException: Failed to connect node to cluster because local flow is different than cluster flow.

So the Cluster Coordinator role was obtained even though the node is disconnected. This shouldn't happen.
