             Summary: Offloading a shut down node will never end until a full reset
                 Key: NIFI-6189
                 URL: https://issues.apache.org/jira/browse/NIFI-6189
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 1.9.1
            Reporter: Nimrod Avni


If a situation occurs where one of your nodes is unresponsive, and you attempt to offload it, it will be stuck in offloading status for ever until a full (not rolling) restart will occur

This is a serious problem considering if your cluster does not have all it's nodes connected you can't operate/create anything in it, for you to do it will require you to shut down your entire cluster and start it over again

my suggestion for a solution is one of :
 # offloading timeout: have a property under the nifi.properties file to indicate how long to wait for a node to finish offloading before considering it disconnected
 # force offload to stop: have an option to force stop the offloading of a node. making it disconnected

I found a hortonworks tread about this same issue
