    Description

      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 the following:

      1. offloading timeout: have a property under the nifi.properties file to indicate how long to wait for a node to finish offloading before forcing it to stop and considering it disconnected
      2. 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
