             Summary: When user clicks 'Disable Transmission' on a Remote 
Process Group, if timeout too long, node drops from cluster
                 Key: NIFI-1609
                 URL: https://issues.apache.org/jira/browse/NIFI-1609
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
            Reporter: Mark Payne


When a user clicks "Disable Transmission" on a Remote Process Group, the web 
request does not complete until the Remote Process Group finishes communicating 
with the remote instance. The default timeout is 30 seconds. As a result, if a 
node is unable to communicate with the remote resource (for instance, a 
firewall prevents the connection), then the web request will timeout (assuming 
the default 30 second timeout), resulting in the node being disconnected from 
the cluster.

When disabling transmission, the web request should return, regardless of 
whether or not the RPG is still communicating with the remote instance.
