----------------------------------
Summary: Remote Process Group in a SSL setup generates Java
Exception
Key: NIFI-4898
URL: https://issues.apache.org/jira/browse/NIFI-4898
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 1.5.0
Environment: NiFi Version 1.5.0
Java 1.8.0_161-b12
CentOS Linux release 7.4.1708
Reporter: Josef Zahner
In a SSL secured NiFi setup, doesn't matter whether it is a cluster or not,
NiFi creates a Java exception as soon as I create a "Remote Process Group". It
doesn't mater which URL (even one which doesn't exists) I insert or if I choose
RAW or HTTP, the error is always the same and occurs as soon as I click "add"
on the "Remote Process Group".
On NiFi 1.4.0 this works without any issues.
Error:
