Mark Payne created NIFI-4632:
--------------------------------
Summary: Site-to-Site failing with default configuration
Key: NIFI-4632
URL: https://issues.apache.org/jira/browse/NIFI-4632
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.5.0
Reporter: Mark Payne
Assignee: Mark Payne
Priority: Critical
Fix For: 1.5.0
With a new install, from 'master' branch I created an Input Port and then a
Remote Process Group pointing to localhost:8080/nifi. When attempting to send
data to my Input Port, nothing appears to happen in the UI. In the logs, I see
the following:
{code}
2017-11-22 09:30:39,918 WARN [NiFi Web Server-184]
o.a.nifi.web.server.HostHeaderHandler Request host header
[<hostname>.local:8080] different from web hostname [localhost(:8080)].
Overriding to [localhost:8080/nifi-api/site-to-site/peers]
2017-11-22 09:30:39,918 WARN [Http Site-to-Site PeerSelector]
o.a.n.r.util.SiteToSiteRestApiClient Failed to parse Json. The specified URL
http://<hostname>.local:8080/nifi-api is not a proper remote NiFi endpoint for
Site-to-Site communication.
requestedUrl=http://<hostname>.local:8080/nifi-api/site-to-site/peers,
response=<h1>System Error</h1>
<h2>The request contained an invalid host header [<hostname>.local:8080] in the
request [/nifi-api/site-to-site/peers]. Check for request manipulation or
third-party intercept. </h2>
{code}
I tried updating nifi.properties to set the "nifi.web.http.host" property to
<hostname>.local and that did resolve the issue... but then I could not connect
to the UI using localhost:8080 but instead had to connect using
<hostname>.local.
This appears to not affect any released versions of NiFi.
