Jeremy Dyer created NIFIREG-167:
-----------------------------------
Summary: NiFi fails to start if invalid NiFi Registry URI is
configured in a controller service.
Key: NIFIREG-167
URL: https://issues.apache.org/jira/browse/NIFIREG-167
Project: NiFi Registry
Issue Type: Bug
Affects Versions: 0.1.0
Reporter: Jeremy Dyer
Fix For: 0.2.0
When configuring a NiFi-registry client within NiFi the user can enter whatever
URI they desire. However if the user enters a URI that does not contain
http/https the URI is not validated. I typed "htp://" for example instead of
"http://";. I restarted nifi and nifi would not restart giving an error in the
logs that is included below. This prevented NiFi from starting without first
manually fixing the controller service entry for the nifi-registry. This seems
to only happen when you "update" the URI for the NiFi-Registry. It seems that
client side validation is not occuring when updating the URI. This allows for
the system to get in an invalid state if someone updates the URI incorrectly.

java.lang.IllegalArgumentException: Cannot create Flow Registry with URI of
