RaymondYap created NIFI-8321:
--------------------------------

             Summary: Add an HttpClient Exception
                 Key: NIFI-8321
                 URL: https://issues.apache.org/jira/browse/NIFI-8321
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.12.1
            Reporter: RaymondYap


* The RemoteProcessGroup will crash Jetty, if the other site of NiFi Cluster disappear(host suddenly shutdown/ instance shutdown terminate...).

* Because of the HttpClient lack of "NoRouteToHostException" exception.

* Although the HttpClient has thrown an "IOException" and the "StandardRemoteGroupPort", has caught the "IOException"
* but the HttpClient never throw "NoRouteToHostException", therefore, "StandardRemoteGroupPort" will never catch the exception and still try to create http connection
