> Priority: Minor

> If i have a RPG configured to use the RAW transport protocol and then switch
> it to use HTTTP transport protocol, it will throw the following error message
> twice before finally correcting itself:
> 2017-01-19 22:10:32,363 ERROR [I/O dispatcher 841]

> Similarly the following ERROR message will be thrown many times when
> switching from HTTP to the RAW transport protocol:
> 2017-01-19 22:13:15,916 ERROR [Timer-Driven Process Thread-10]
> o.a.nifi.remote.StandardRemoteGroupPort
> RemoteGroupPort[name=outport2,targets=http://<hostname>:9090/nifi/] failed to
> communicate with http://<hostname>:9090/nifi/ due to
> org.apache.nifi.remote.exception.HandshakeException:
> org.apache.nifi.remote.exception.ProtocolException: Expected to receive
> ResponseCode, but the stream did not have a ResponseCode
> With both these scenarios, the RPG will eventually correct itself and start
> working again. User may be hesitant to wait once they start seeing these
> ERRORS and instead stop the RPG since the self correction does not occur
> rapidly.
