Hi,
We have a Nifi 1.1 cluster, and one of the nodes that has previously been
working fine, is now refusing to start, throwing this exception:
2017-02-03 16:04:48,588 ERROR [main] o.a.nifi.controller.StandardFlowService
Failed to load flow from cluster due to:
org.apache.nifi.cluster.ConnectionException: Failed to connect node to cluster
