Mark Payne created NIFI-871:
-------------------------------
Summary: Site-to-Site does not report the actual hostname that it
was trying to connect to when it fails to connect
Key: NIFI-871
URL: https://issues.apache.org/jira/browse/NIFI-871
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Mark Payne
Fix For: 0.4.0
In testing the patch provided for NIFI-868, I set the nifi properties to
advertise the hostname as "otherhost". Site-to-Site, of course, failed to
connect, but rather indicating that it could not connect to otherhost, it
simply indicated that it was the RemoteProcessGroup connected to
http://localhost:8080/nifi. This is misleading because it leads the user to
believe that the Remote Process Group is having trouble connecting to
localhost, when in reality it is attempting to connect to "otherhost". We
should indicate which host we are connecting to when providing an error like
this.
