------------------------------------
Summary: NiFi RPG errors when switching between transport
protocols.
Key: NIFI-3377
URL: https://issues.apache.org/jira/browse/NIFI-3377
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.1.0
Reporter: Matthew Clarke
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.
