-----------------------------------
Summary: HTTP Site-to-Site can't update remote peer topology if
the "bootstrap url" is down
Key: NIFI-2459
URL: https://issues.apache.org/jira/browse/NIFI-2459
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.0.0
Reporter: Koji Kawamura
To establish a Site-to-Site protocol, a client NiFi uses the remote NiFi API
url that is specified as 'URL' at the creation of a Remote Process Group (let's
call it as 'bootstrap url').
Currently, HTTP Site-to-Site keeps using the same 'bootstrap url', even if the
remote node goes down. If the bootstrap node went down, Site-to-Site data
transfer will keep working, but it can't update remote peer topology.
RAW socket version cares about this scenario by asking updated peer information
with every nodes that it has connected before, until it gets a successful
response.
HTTP version should follow how RAW version handles this.
