             Summary: Node can join the cluster with processors running when cluster state for that processor is stopped
                 Key: NIFI-5619
                 URL: https://issues.apache.org/jira/browse/NIFI-5619
             Project: Apache NiFi
          Issue Type: Bug

When the cluster state for a processor is stopped, it is possible for a node to join the cluster with that particular processor running.  The UI will show the processor as stopped, but going to the cluster summary and viewing the node-specific status of that processor will show it's running on the node that joined.

To reproduce this:
# Build the Node Decommissioning [PR 3010|https://github.com/apache/nifi/pull/3010]
# Create a two-node cluster, does not need to be secure
# Create a flow with a GenerateFlowFile processor connected to an UpdateAttribute processor
# Start the GenerateFlowFile processor to let flowfiles queue in the connection to UpdateAttribute
# Disconnect the second node from the cluster
# Decommission the second node from the cluster
# Restart the node that was decommissioned from the cluster
# Once the node is reconnected, in the UI the GenerateFlowFile processor will look like it is stopped
# Go to the Cluster Summary UI and click on the View Processor Details icon which will show the processor still running on the node that was reconnected
