Joseph Percivall created NIFI-2863:
--------------------------------------
Summary: A remote process group pointed to a host without the
trailing "/nifi" will fail with mis-leading bulletins
Key: NIFI-2863
URL: https://issues.apache.org/jira/browse/NIFI-2863
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 1.0.0
Reporter: Joseph Percivall
To replicate:
1: Set up NiFi instance on port 8080 and remote port 8081 (unsecure S2S)
2: create input port
3: create RPG pointing to "http://localhost:8080";
This RPG will correctly get the instance name, listing of ports and port status
but when transmission is enabled and a flowfile is queued to be sent the
following error is generated:
"RemoteGroupPort[name=test1,target=http://localhost:8080] failed to communicate
with http://localhost:8080 due to org.codehaus.jackson.JsonParseException:
Unexpected character ('<' (code 60)): expected a valid value (number, String,
array, object, 'true', 'false' or 'null')
at [Source: java.io.StringReader@44d519ce; line: 3, column: 2]"
Looking at the logs there is this message:
2016-10-04 14:11:34,298 WARN [Timer-Driven Process Thread-2]

This should either be fixed (to allow without "/nifi") or explicitly validated.
